Mohammed*](https://science.gsfc.nasa.gov/sed/bio/ibrahim.mohammed \"Ibrahim N. Mohammed\")\n\n## **What is NASAaccess?**\n\n*NASAaccess* is a software application in the form of a [R](https://www.r-project.org/about.html) package, a [conda](https://docs.conda.io/en/latest/) package, and a [Tethys](https://www.tethysplatform.org/) web application. *NASAaccess* software can generate gridded ascii tables of climate [CMIP5](https://pcmdi.llnl.gov/mips/cmip5/ \"Coupled Model Intercomparison Project Phase 5\"), [CMIP6](https://pcmdi.llnl.gov/CMIP6/ \"Coupled Model Intercomparison Project Phase 6\"), and earth observation remote sensing data ([GPM](https://gpm.nasa.gov/data/directory \"Global Precipitation Measurement\"), [TRMM](https://gpm.nasa.gov/missions/trmm \"Tropical Rainfall Measuring Mission\"), [GLDAS](https://ldas.gsfc.nasa.gov/gldas \"Global Land Data Assimilation System\")) needed to drive various hydrological models (e.g., [SWAT](https://swat.tamu.edu/ \"Soil \u0026 Water Assessment Tool\"), [VIC](https://github.com/UW-Hydro/VIC \"Variable Infiltration Capacity\"), [RHESSys](https://github.com/RHESSys/RHESSys \"The Regional Hydro-Ecological Simulation System\"), ...etc.). The *NASAaccess* Tethys web-based application can be used for accessing, reformatting, and visualizing climate and earth observation remote sensing gridded time series data as well.\n\n## **Where to find the NASAaccess software?**\n\n-   R package can be downloaded from GitHub at \u003chttps://github.com/nasa/NASAaccess\u003e.\n\n-   Conda package can be installed directly from *Anaconda* by searching for `r-nasaaccess`.\n\n-   Tethys web-based application can directly installed from GitHub at \u003chttps://github.com/imohamme/tethys_nasaaccess\u003e.\n\n## **How NASAaccess software is distributed?**\n\n*NASAaccess* is an open-source software package under [NASA Open Source Agreement v1.3](https://opensource.org/license/nasa1-3-php/).\n\n## **What is needed to install the NASAaccess software on my local machine?**\n\n### **R Library**\n\nOn a local machine the user should have installed the following programs as well as setting up a user account. The list below gives a summary of what is needed to be done prior to work with NASAaccess software on any local machine:\n\n-   [Installing R software](https://www.r-project.org/)\n\n-   [Installing Rstudio software](https://posit.co/) (OPTIONAL)\n\n-   *NASAaccess* R package needs a user registration access with [Earthdata](https://www.earthdata.nasa.gov/). Users should set up a registration account(s) with [Earthdata](https://www.earthdata.nasa.gov/) login as well as well as authorizing [NASA](https://www.nasa.gov/ \"The National Aeronautics and Space Administration\") [GES DISC](https://disc.gsfc.nasa.gov/) data access. Please refer to \u003chttps://disc.gsfc.nasa.gov/information/documents\u003e Data Access section for further details.\n\n-   [*curl*](https://curl.se/) software . Since Mac users have [*curl*](https://curl.se/) as part of macOS build, Windows users should make sure that their local machines build have [*curl*](https://curl.se/) installed properly.\n\n      -   Checking if you can run [*curl*](https://curl.se/) from your command prompt. Type `curl --help` and you should see the help pages for the [*curl*](https://curl.se/) program once everything is defined correctly.\n\n-   Within Rstudio or R terminal run the following commands to install *NASAaccess*:\n\n    -   `library(devtools)`\n\n    -   `install_github(\"nasa/NASAaccess\", build_vignettes = TRUE)`\n\n    -   `library(NASAaccess)`\n\nWithin the Rstudio help tab the user can verify that the package has been installed and browse the help pages of the various functions of *NASAaccess*. The [GES DISC](https://disc.gsfc.nasa.gov/) user registration access logging information will be processed by masking (i.e., not displaying the lieteral typed text as input) on most but not all platforms. Without providing [GES DISC](https://disc.gsfc.nasa.gov/) user registration access logging information, the user will receive '*You need to provide your Earthdata GES DISC login to proceed...*' message.\n\n### **Conda Package**\n-   *NASAaccess* conda package needs a user registration access with [Earthdata](https://www.earthdata.nasa.gov/). Users should set up a registration account(s) with [Earthdata](https://www.earthdata.nasa.gov/) login as well as well as authorizing [NASA](https://www.nasa.gov/ \"The National Aeronautics and Space Administration\") [GES DISC](https://disc.gsfc.nasa.gov/) data access. Please refer to \u003chttps://disc.gsfc.nasa.gov/information/documents\u003e Data Access section for further details.\n\n    -   Creating the *.netrc* file at the user machine *Home* directory and storing the user [NASA](https://www.nasa.gov/ \"The National Aeronautics and Space Administration\") [GES DISC](https://disc.gsfc.nasa.gov/) logging information in it is done automatically to execute the *NASAaccess* package commands. Accessing data from NASA servers is further explained at [Here](https://wiki.earthdata.nasa.gov/display/EL/How+To+Access+Data+With+cURL+And+Wget). The [GES DISC](https://disc.gsfc.nasa.gov/) user registration access logging information will be processed by masking in the terminal on any major OS. Without providing [GES DISC](https://disc.gsfc.nasa.gov/) user registration access logging information, the user will receive '*You need to provide your Earthdata GES DISC login to proceed...*' message.\n    \n    \n-   To install *NASAaccess* package in a conda environment run the following:\n\n``` python\nconda install -c conda-forge r-nasaaccess\n```\n\n### **Tethys web-based Application**\n\nFull details on installing the web-based application of *NASAaccess* on single machines and local servers can be found at [readthedocs](https://nasaaccess.readthedocs.io/en/latest/nasaaccess_tethys.html).\n\n## **Is there a walk through examples for NASAaccess software?**\n\nSoftware users are encouraged to visit (\u003chttps://imohamme.github.io/NASAaccess/\u003e) to learn more on *NASAaccess* functionality and capabilities.\n\n## **How to cite R NASAaccess package?**\n\n```{r}\ncitation(package = 'NASAaccess')\n\n```\n\n## Reference\n\nMohammed, I.N., Bustamante, E.G.R., Bolten, J.D., Nelson, E.J., 2023.
