Name: NOAA Global Data Assimilation System (DA) Test Data | ||
Description: | | ||
The "[Unified Forecast System (UFS)](https://ufs.epic.noaa.gov/)" is a community-based, coupled, comprehensive Earth Modeling System. It supports "[multiple applications](https://ufs.epic.noaa.gov/applications/)" with different forecast durations and spatial domains. The "[Global Data Assimilation System (GDAS)(https://github.com/NOAA-EMC/GDASApp)" Application (App) is being used as the basis for uniting the "[Global Workflow](http://NOAA-EMC/global-workflow)" and Global Forecast System (GFS) model with "[Joint Effort for Data assimilation Integration (JEDI)](https://jointcenterforsatellitedataassimilation-jedi-docs.readthedocs-hosted.com/en/latest/)" capabilities. | ||
<br/> | ||
<br/> | ||
The National Centers for Environmental Prediction (NCEP) use GDAS to interpolate data from various observing systems and instruments onto a three-dimensional grid. GDAS obtains its data through several observation types: surface, balloon, wind profilers, aircraft reports, buoys, radar, and satellite. This gridded output data is then used to initialize the GFS model. GDAS can be used in standalone mode to run forward operators and variational data assimilation (DA) for evaluation/development purposes. In the GDAS App, it supports GFS/GDAS cycled forecasts in the Global Workflow. Currently, GDAS primarily uses GSI for its data assimilation and cycling, but efforts are underway to replace GSI with JEDI. | ||

Contact: For questions regarding data content or quality, post on the ufs-community forum at https://github.com/orgs/ufs-community/discussions or email [email protected]. For any questions regarding data delivery or any general questions regarding the NOAA Open Data Dissemination (NODD) Program, email the NODD Team at [email protected]. | ||
<br /> We also seek to identify case studies on how NOAA data is being used and will be featuring those stories in joint publications and in upcoming events. If you are interested in seeing your story highlighted, please share it with the NODD team by emailing [email protected] | ||

Name: ArcticDEM | ||
Description: ArcticDEM - 2m GSD Digital Elevation Models (DEMs) and mosaics from 2007 to the present. The ArticDEM project seeks to fill the need for high-resolution time-series elevation data in the Arctic. The time-dependent nature of the strip DEM files allows users to perform change detection analysis and to compare observations of topography data acquired in different seasons or years. The mosaic DEM tiles are assembled from multiple strip DEMs with the intention of providing a more consistent and comprehensive product over large areas. ArcticDEM data is constructed from in-track and cross-track high-resolution (~0.5 meter) imagery acquired by the Maxar constellation of optical imaging satellites. | ||

Name: EarthDEM | ||
Description: EarthDEM - 2m GSD Digital Elevation Models (DEMs) and mosaics from 2002 to the present. The EarthDEM project seeks to fill the need for high-resolution time-series elevation data in non-polar regions. The time-dependent nature of the strip DEM files allows users to perform change detection analysis and to compare observations of topography data acquired in different seasons or years. The mosaic DEM tiles are assembled from multiple strip DEMs with the intention of providing a more consistent and comprehensive product over large areas. EarthDEM data is constructed from in-track and cross-track high-resolution (~0.5 meter) imagery acquired by the Maxar constellation of optical imaging satellites. Only a portion of the worldwide EarthDEM dataset is available publicly. Federally-funded researchers may access the entire dataset via NASA CSDA's Smallsat Data Explorer (see Data at Work section). | ||
