Corrosion risk due to relative humidity

by EarthdataForumContributor » Fri May 01, 2020 12:38 pm America/New_York

I am working in one project, trying to quantify the corrosion risk of bridge in Texas. One important step is to get the annual relative humidity in Texas. So I want to get the access to it.
I can’t create a ASDC account. Could you help me with that?

For your convenience we are providing you with a "Quick Start User Guide".
Within this quide you should be able to find the data for your research.

Quick Start User’s Guide:

Here are instructions for accessing/downloading solar radiation data.

Solar and meteorological parameters can be accessed in the POWER web site via the Data Access Viewer (DAV) 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.
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", or "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 Folders of your choice 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".

A new users guide: (/data-access-viewer/POWER_DAV_USER_GUIDE.pdf)
You may also download all data parameters using API calls described at (/docs/v1/).

The methodology documentation ( includes updated definitions and parameter uncertainty information derived using surface measurements.

Dear Mr. Zhang,

Were you able to obtain the data products you sought? Your application to infrastructure is one that we'd like to support. Are there additional parameters that might be of use?
