GLDASpolyCentroid
Generate daily minimum and maximum air temperature data from NASA GLDAS modeled remote sensing products at polygon centroid.
GPM NRT
Generate Near Real Time (NRT) rainfall from NASA GPM remote sensing products.NASA GLDAS modeled remote sensing products within watershed boundaries.
GLDAS
Generate daily minimum and maximum air temperature data from NASA GLDAS modeled remote sensing products within watershed boundaries.
GPMpolyCentroid
Generate daily rainfall data from NASA GPM remote sensing products at polygon centroid.
GPM
Generate daily rainfall data from NASA GPM remote sensing products within watershed boundaries.
CMIP5 collection
Generate daily rainfall or air temperature (minimum and maximum) data from NASA NEX-GDPP-CMIP5 remote sensing climate change data products within watershed boundaries.
CMIP6 collection
Generate daily rainfall or air temperature (minimum and maximum) data from NASA NEX-GDPP-CMIP6 remote sensing climate change data products within watershed boundaries.
The NASAaccess Tethys App is a web platform developed for accessing and visualizing climate and weather data from NASA's Earth Observing System Data and Information System (EOSDIS). More information about methodologies used in NASAaccess can be obtained from Mohammed et al., 2018, McDonald et al., 2019, and NASAaccess demonstration web pages.
NASAaccess App needs a user registration access with Earthdata. NASAaccess App maintainer (server admin\local user) installing the app on a local server\machine should set up a registration account(s) with Earthdata login as well as well as authorizing NASA GES DISC data access. Please refer to https://disc.gsfc.nasa.gov/data-access for further details.
After registration with Earthdata NASAaccess App maintainer should create a reference file '.netrc' with Earthdata credentials stored in it to streamline the retrieval access to NASA servers. Creating the '.netrc' file at the maintainer machine 'Home' directory and storing the user NASA GES DISC logging information in it is needed to execute the NASAaccess App functions. Accessing data at NASA servers is further explained at EarthData wiki.

If you have questions, comments, or requests for further functionality please contact Ibrahim Mohammed.
If you have previously run the NASAaccess function, you should have received a 6-digit access code.
Please input your access code below and click the "Download" button to download the files from your NASAaccess query.
If you have previously run the NASAaccess function, you should have received at 6-digit access code.
Please input your access code below and click the "Plot" button to plot the data from your NASAaccess query.
Depending on the watershed size and the date range you selected, the nasaaccess process may take some time. Please provide your email here and we will contact you with a 6 digit access code for downloading your data when the process is complete.
Your email will only remain in our database until your access code has been sent out. The access code you receive will then be valid for 3 days.
