Description
Winds play important role in hydrological cycle and water quality. Atmospheric moisture moves around the globe because of winds. Wind also affects rate of evaporation. Contaminant plumes in waterbodies get pushed by winds.

Output Data Format Options
| Parameter | DataType | Description | Comments |
|---|---|---|---|
| Source | Drop-down list | Time-series data source | Valid sources: nldas, gldas, and ncei. |
| NCEI Station ID | String | NOAA NCEI station identification number e.g. GHCND:USW00013874 | Used only when “ncei” is selected for “Source”. Station identifiers can be obtained from NOAA’s tool at https://www.ncdc.noaa.gov/cdo-web/datatools/findstation |
| Start Date | String | Start date for the output timeseries. e.g., 01/01/2010 | Data Availability nldas: hourly 1/1/1979 – Present (~4-day lag); North America @ 0.125 deg resolution. gldas: 3-hourly 1/1/2000-Present (~1-month lag); Global @ 0.250 deg resolution. ncei: depends upon selected station. By default, 'GHCND' stations are provided at daily timesteps, 'COOP' stations are povided at hourly timesteps. |
| End Date | String | End date for the output timeseries. e.g., 01/01/2010 | |
| Location Option | Drop-down list | Location of interest options. | Valid options: Latitude/Longitude, Catchment Centroid. Output time-series is returned for the latitude/longitude at the centroid of the NHDPlusV2.1 catchment when 'catchment (COMID)' is selected. |
| Latitude | Number | Latitude coordinate for the output timeseries. e.g., 33.925575 | Used only when 'Latitude/Longitude' is selected for 'Location Option'. |
| Longitude | Number | Longitude coordinate for the output timeseries. e.g., -83.356893 | Used only when 'Latitude/Longitude' is selected for 'Location Option'. |
| Catchment COMID | String | NHDPlusV2.1 catchment COMID. | Used only when 'catchment Centroid' is selected for 'Location Option'. |
| Local Time | Drop-down list | Time zone for the timestamp in output time-series. | Valid options: yes, GMT. All data sources can be returned in Greenwich Mean Time (GMT) but only ncei, nldas, and gldas time-series can be returned in local time. |
| Temporal Resolution | Drop-down list | Temporal resolution/timestep of the output time-series. | Valid options: hourly, 3-hourly, daily, monthly. Daily and Monthly resolution is available for all data sources. Hourly resolution is available only for nldas. 3-hourly resolution is available for gldas. |
| Output Date Format | String | Format of the returned numeric values. | Valid options: E E0, E1, E2, E3, e, e0, e1, e2, e3, F, F0, F1, F2, F3, G, G0, G1, G2, G3, N, N0, N1, N2, N3, R. Details are available in the table below. |
