Additional detail for the web service access is available at the REST API Documentation. Category: Documents. The ECOSTRESS mission measures the temperature of plants from space, and provides both land surface temperature (LST) and emissivity (Level-2 products) at a spatial resolution of ~70 m × 70 m (Hook et al., 2019; Hulley et al., 2019).LST is one of the important parameters for studying processes at the land-atmosphere interface which measures Earth's surface temperature rather than air temperature. Estimate ECOSTRESS band emissivity by regression from MASTER TIR bands – Using ASTER spectral library data and MASTER/ECOSTRESS response functions ECOSTRESS : NASA's next generation mission to measure evapotranspiration from the international space station. This MATLAB function reads spectral data from the specified ECOSTRESS spectrum files. Read spectral files related to water, vegetation, soil, and concrete from the ECOSTRESS spectral library. Simon J. Hook of NASA/JPL is the PI of the ECOSTRESS instrument development and science investigation. This example uses 1) the spectral signatures in the ECOSTRESS spectral library as the reference spectra and 2) a data sample from the Jasper Ridge dataset as … Names of the ECOSTRESS files, specified as a character vector, string scalar, cell array of character vectors, or vector of strings. ***** Name Last modified Size Description. The sample spectra and bands are stored in BLOB objects in the database, so you probably don’t want to access them directly. These data are generated from the Level-2 land surface temperature and emissivity product (L2_LSTE), in conjunction with … This Interface Control Document (ICD) provides specific information about the interfaces between the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) Science Data System (SDS) and the Land Processes (LP) Distributed Active Archive Center (DAAC).

When performing QC, the detailed information should be noted in a QC document (spreadsheet, list, form) and then, if using a digitization tracking spreadsheet, in this as well. This download area allows you to download the ECOSTRESS spectral library (formerly ASTER spectral library) without using the search tool. ECOSTRESS instrument. out of 4. With Landsat 8 SR data as inputs, the ECOSTRESS LST was sharpened to 30-m resolution with a set of EC box sizes ranging from 90 to 810 m with an interval of 90 m. The users' guide is designed to be a living document that describes the ECOSTRESS Land Surface Temperature and Emissivity (LST&E) product. ECOSTRESS is a thermal radiometer built by National Aeronautics and Space Administration (NASA)'s Jet Propulsion Laboratory (JPL) that measures thermal infrared radiation (TIR) in five bands from 8‐ to 12.5‐μm wavelengths, plus an additional sixth band at 1.6 μm for geolocation and cloud detection ( ecostress.jpl.nasa.gov ).
