SWOT Calibration / Validation Plan (Initial Release) This document provides the scope of planned Calibration and Validation (Cal/Val) activities for the SWOT Mission. It contains an overview of the objectives of Cal/Val work, details of planned Cal/Val activities, and provides the organizational context for how the work will be undertaken.
SWOT Project Mission Performance and Error Budget This document presents the top-down error budget for the SWOT mission and its ability to meet the scientific requirements. It includes all the different systems and subsystems that have a significant contribution to the overall performance of the mission. It is structured in several parts corresponding to the key error contributions for both oceanography and hydrology, with a discussion of the main contributors to the global performance: Flight System, Payload and Payload Instruments, S/C bus, Algorithms, and Mission System. The error budget presented in this document forms the basis for the performance requirements for the SWOT Mission levied across all these elements
SWOT Science Requirements Document The SWOT mission is a partnership between two communities, physical oceanography and hydrology, to share high vertical accuracy and high spatial resolution topography data produced by payload configuration, whose principal instrument is the Ka-band Radar Interferometer (KaRIn) for making swath measurement of the elevation of land surface water and ocean surface topography. The broad scientific objectives specified by the NRC decadal review have been refined by community involvement in open workshops and the guidance of an informal science team before the missions' Phase A, and further improved by the missions' Science Definition Team during Phase A. This document summarizes the scientific objectives for each community.
SWOT Orbit Information Information on SWOT orbit characteristics and requirements, as well as reference orbit and swath files.
SWOT Mission Science Document In October 2007, a SWOT Science Working Group (SWG) was formed under the auspices of NASA and CNES with participants from the international communities of oceanography and land surface hydrology. The SWG was charged to provide scientific guidance for the development of the mission, including science objectives and requirements, science payload, orbit selection, and data products. Since the inaugural meeting in October 2007, the SWG has met eight times. Additionally, a town hall meeting on SWOT was held in the 2008 American Geophysical Union (AGU) Fall Meeting. This document summarizes the findings from these meetings with a purpose to provide information on the potential opportunities in science investigation and applications as well as on the preliminary design of the SWOT mission concept.

Development of Barotropic and Baroclinic Tide Models in Support of the SWOT Mission First-mode baroclinic tides have typical wavelengths in the deep ocean of order 100-170 km for semidiurnal tides, double that for diurnal tides. Higher modes have shorter scales. These tides thus fall directly into the prime mesoscale and submesoscale regime that SWOT is designed to study. It will be critical to remove as much of this tidal variability in SWOT data as possible. Our project aims to develop both barotropic and baroclinic tidal models to support this goal and to deliver models to the SWOT project teams that can be employed for the initial processing of SWOT data.
PI: Richard Ray
Expanding Altimetry Outreach: An Investigation to Federate and Promote Outreach for the SWOT Mission We propose to use the possibilities of the SWOT mission to continue to expand outreach, be it educational & public outreach, or application outreach, to new publics, and new subjects, including and especially hydrology. For that, we will build upon existing material and new Investigators works, develop new link lists, and also new material when none is available.

Fluxes of Heat, Carbon, and Oxygen at SWOT Scales There are many complex issues involved in maximizing the usefulness of SWOT observations. Our particular focus is on better understanding how SWOT may aid in better establishing the role played by submesoscale phenomena in mediating fluxes of the biogeochemical tracers. Can SWOT help determine submesoscale contributions to global budgets? What are the primary lateral and temporal scales responsible for transport? Which submesoscale processes play the most important roles in vertical fluxes? We are addressing these questions with suites of submesoscale-resolving regional simulations, described briefly in this document.

Understanding SWOT Measurements in Coastal Wetlands The Surface Water and Ocean Topography (SWOT) mission will enable estimation of water level and velocity along the coast and within large rivers. However, SWOT's capabilities and limitations in coastal wetlands remains to be assessed. Coastal wetlands are complex systems characterized by a mosaic of various vegetation types covering the water surface and are interspersed with numerous rivers and channels of different sizes. Our overall goal is to assess the potential and limitations of SWOT to measure and monitor hydrodynamic processes in coastal wetlands, and to define the SWOT science products specific to coastal wetlands.

Modeling Internal Wave Signals and their Predictability for SWOT We are working with high-resolution global simulations, of the HYbrid Coordinate Ocean Model (HYCOM) and the MITgcm, that are simultaneously forced by atmospheric and oceanic fields and that therefore resolve both mesoscale eddies and internal wave motions.
PI: Brian Arbic
Exploiting Ocean Observations to Separate Mesoscale and Submesoscale Variability A critical step in interpreting the SWOT signal will be to distinguish the mesoscale signals (wavelength > 50 km) from the other signals that will be detected by SWOT (e.g., submesoscale features, internal waves and tides, swell). This is a nontrivial problem, as these processes are not well understood or modeled. A further complication is that SWOT will have a temporal resolution of 10-20 days, making it difficult to identify the quickly evolving submesoscale field and internal waves. Tackling this problem requires a better understanding of ocean dynamics across the range of scales and regimes that SWOT will measure.
PI: Kyla Drushka

Water Level and Discharge Estimation with a Polynomial Surrogate Model for Uncertainty Quantification and Data Assimilation - Application to a Real Test Case: The Garonne Valley The group is composed of CECI (CERFACS/CNRS, Toulouse, France) and LNHE (EDF R&D, Chatou, France). It gathers expertise in hydraulic modeling (TELEMAC-MASCARET software) and applied mathematics with a focus on uncertainty quantification (UQ) (sampling, analysis of variance, surrogate models) and data assimilation (DA) (ensemble-based methods, filtering algorithms, variational methods). The group has been working together for several years; the most significant developments stand in the implementation of Kalman Filter derived algorithm for model state and parameters correction via DA of inset observations and its operational use for flood forecasting and water resource management. A perspective for these studies, developed here, is to use Surface Water and Ocean Topography (SWOT) data to improve hydraulic model parameters and results and consequently improve water level and discharge simulation and forecast.

Characterization of Global Internal Tides at High Horizontal Resolution This project aims to improve the prediction and characterization of internal-tide sea surface displacements using global numerical simulations with 1/100 (~1 km horizontal resolution. The high resolution simulations are conducted using the linearized Coupled-mode ShallowWater model (CSW; Kelly et al., 2016), which can resolve small-scale internal tides that are absent in coarserresolution general circulation models (which typically have horizontal resolutions of 4-10 km). The increased resolution improves the representation of internal tides throughout the global ocean, however the largest improvements occur in regions where internal tides have short wavelengths, such as coastal seas, regions of complex bathymetry, and areas of energetic mesoscale circulation.

Participation in the SWOT Science Team: Marine Geophysics One of the secondary objectives of the SWOT mission is marine geophysics. The current accuracy of the ocean surface slope derived from traditional altimetry is about 2 microradians at 13 km wavelength, which is equivalent to 2 milligals of accuracy. SWOT, with its smaller footprint and additional cross-track slope measurement, could improve the gravity accuracy by perhaps an order of magnitude and also improve spatial resolution especially on the shallow continental margins.

The ultimate goal is to enhance our understanding of the impact of finescale processes on biochemical variables. We will focus on a range of scales (30-100 km) traditionally not resolved by conventional altimeters.

River Discharge Estimation Under Uncertainty from Synthetic SWOT-type Observations Using Variational Data Assimilation Variational data assimilation has been applied for discharge estimation under uncertainties in river bathymetry and bed roughness using the hydraulic model SIC2. Synthetic WSE measurements, which emulate the spatial and temporal sampling of the SWOT mission, are assimilated for the Garonne River downstream reach. Similar tests have been carried out on the Po and Sacramento Rivers using the SWOT hydrology simulator developed at JPL. We investigate simultaneous estimation of discharge, river bathymetry and bed roughness in the framework of the extended control vector approach.

New Dynamical Tools for Submesoscales Characterization in SWOT Data The altimetry mission SWOT will provide Sea Surface Height (SSH) data-sets at unprecedented resolution (10-100km) with a 2D coverage in space. Such a data-set requires development of new diagnostic tools to unveil different dynamical aspects of the mesoscales (horizontal scales around 300km) and submesoscales (around 30km) that can be extracted from the SSH signal.
Assimilation and Interpretation of High-Wavenumber Variability in the Ocean for SWOT The objective of our research in support of SWOT is to develop 4-dimensional variational assimilation (4d-var) methods that include both quasi-geostrophic and tidal motions in order to build the capabilities to map, evaluate, and interpret SWOT observations, with a specific focus on the California Current region, which has been identified as one of the target regions for calibration and validation of SWOT (Wang et al., 2016). Our aim is to distinguish balanced, geostrophic motions from the myriad other processes that influence SSH variability at the ocean surface.

SWOT Preparations for Ground-truthing, Discharge Product Development and Water Management Applications in Asian River Systems With rising population growth and increasing demand for resources, surface water is being redistributed and artificially managed to the extent that there are few pristine river basins left today in populated regions without the strong human footprint caused by water diversions, barrages, dams and irrigation projects. The current reality is that in these populated regions of the world, it has become intractable to have accurate knowledge of the management component of water for physically predicting the surface water component of the human-impacted water cycle.

SWOT Simulator for Ocean Science This software simulates SWOT observations of sea surface height (SSH) that can be applied to an ocean general circulation model (OGCM), allowing the exploration of ideas and methods to optimize information retrieval from the SWOT Mission in the future. From OGCM SSH inputs, the software generates SWOT-like outputs on a swath along the orbit ground track and adds measurement error and noise, which are generated according to technical characteristics published by the SWOT project team. Not designed to directly simulate the payload instrument performance, this SWOT simulator aims at providing statistically realistic outputs for the science community with a simple software package released as an open source in Python. The software is scalable and designed to support future evolution of orbital parameters, error budget estimates from the project team and suggestions from the science community. View the full manual.
