3 hour windspeed data

by EarthdataForumContributor » Mon Apr 20, 2020 12:00 pm America/New_York

I found this site, but have no idea how to find the data referenced here - https://asdc.larc.nasa.gov/project/POWER
Specifically, we are looking to create a wind speed map for Puerto Rico with some finer spatial resolution than what we find in reanalysis data and wanted to explore the wind speed at 3 hour intervals (50 meters) and 10 meters (around airports).
Please help.

Thank you for contacting us with an interest in wind data.

On June 13, 2018 the old SSE web site was replaced with the new data web portal at https://power.larc.nasa.gov with improved solar and meteorology data and greatly enhanced capabilities to facilitate access to NASA's solar insolation and meteorological data parameters. Rest assured that all parameters currently on SSE are now available at the new POWER web site although the parameters might be organized differently.

**Currently, 3-hourly and hourly irradiation, temperature, wind and rainfall data are not available.**

A new users guide https://power.larc.nasa.gov (/data-access-viewer/POWER_DAV_USER_GUIDE.pdf) and API documentation https://power.larc.nasa.gov (/docs/v1/) have been developed to ease the transition to the new web portal.

You may also download all data parameters using API calls described at https://power.larc.nasa.gov (/docs/v1/).

The methodology documentation (https://power.larc.nasa.gov/docs/methodology/) includes updated definitions and parameter uncertainty information derived using surface measurements.

The data obtained from NASA's POWER website are public domain and free of any charges or fees. You may use them in your research, publications, and commercial applications with the request that you acknowledge usage (https://power.larc.nasa.gov/).

Here are "Quick Start" instructions for accessing solar and meteorological data.

Solar and meteorological parameters can be accessed in the POWER web site via the Data Access Viewer (DAV) https://power.larc.nasa.gov/data-access-viewer/. When the DAV page opens you may click the “Access Data” box and/or check the “Do not show ...” box to avoid loading the splash Page on subsequent visits.

FOR WIND Data:
1. In the DAV page that is now visible, in Section 1 select "SSE-Renewable Energy" or "Sustainable Buildings" or "Agroclimatology".
2. Section 2. Select "Daily","Interannual", or Climatology.
3. Section 3. Enter the site latitude and longitude.
4. In Section 4, Select the Time Extent (Enter Start time and End time).
5. In Section 5, Select Output File Format of your choice.
6. In Section 6, Select "Meteorology Wind" Folder pertaining to your research.
The parameters that are available for the Select User Community and Time Extent are listed in Parameters Folders. Each folder can be opened by clicking on the intersection of the horizontal and vertical branch associated with each folder. Individual data parameters are selected/deselected by clicking on each parameters or all parameters in a folder can be selected/deselected by clicking on the folder itself.
7. Click the “Submit” button in Section 7. The resulting page will provide time series plots of the selected data parameters. To download data in the previously selected format click the appropriate box under the "Output Files".

Additionally, if you have questions about the data or how to use it , please feel free to ask experts your questions on the Earthdata Forum.

I'm having trouble with the API, do you have any suggestions on who to contact?
