ATLAS/ICESat-2 L3A Calibrated Backscatter Profiles and Atmospheric Layer Characteristics V002. Also changed the value of R snow to 0.8 from 0.6. This data set (ATL09) contains calibrated, attenuated backscatter profiles, layer integrated attenuated backscatter, and other parameters including cloud layer height and atmospheric characteristics obtained from the data. This webinar was originally presented on July 23, 2019... NASA Earthdata Search is a map-based interface where a user can search for Earth science data, filter results based on spatial and temporal constraints, and order data with customizations including re-formatting, re-projecting, and spatial and parameter subsetting.
For more information, see our It appears your Web browser is not configured to display PDF files. The following table describes the subsetting and reformatting services that are currently available for ICESat-2 data via theTo convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. The relative positions of the 6 beams on the surface provides the capability to determine regional and local surface slope.
Added Table 4.3 on page 55. In Section 4.6.2.1, updated the input GOME data set for surface reflectance from a 1x1 degree to the new 0.25x0.25 degree data set. Each beam pair contains a strong and weak beam. Le satellite est conçu pour fonctionner au moins 3 ans (avec un objectif de 5 ans) et il emporte assez d' ergols pour assurer son fonctionnement durant 7 ans. ICESat-2 est un satellite stabilisé sur 3 axes d'une masse de 1 514 kg utilisant une plate-forme LEOStar-3. 2 0 obj

ATLAS/ICESat-2 L3A Calibrated Backscatter Profiles and Atmospheric Layer Characteristics V003. ICESat-2 (short for Ice, Cloud and land Elevation Satellite), slated to launch in 2018, will use lasers and a very precise detection instrument to measure the elevation of Earth’s surface. There are also options for downloading via a command line or client. Data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system or through our Application Programming Interface (API). Please read this special note first before you proceed further.. You can find examples quickly using the search box below. Comprehensive Examples. Engineers are building and testing the Advance Topographic Laser Altimeter System (ATLAS) for the ICESat-2 mission at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
