TAP API provides public access to the following capabilities:

Capability Link Summary
Wind data for a point on the map https://dw-tap.nrel.gov/on_map Click on the map to select the desired location. You can also choose the output format.
Wind data for a given address https://dw-tap.nrel.gov/by_address After providing a valid address, you will be able to see wind data for that location. You can also choose the output format.
Energy Estimation(NEW) https://dw-tap.nrel.gov/energy Choose a point on the map and a power curve to estimate the amount of energy produced.

The capabilities listed below allow to change highlighted parameters in specific requests (read more about parameters):

Capability Example API call Summary
Plot monthly averages https://dw-tap.nrel.gov/monthly?height=35.00m&lat=39.7412&lon=-105.1686&year=2013 Aggregate to monthly averages and show one or several years of model data.
12x24 (hourly x monthly) summary https://dw-tap.nrel.gov/12x24?height=35.00m&lat=39.7412&lon=-105.1686 This summary allows seeing diurnal and seasonal patterns in wind data.
Wind rose https://dw-tap.nrel.gov/windrose?height=35.00m&lat=39.7412&lon=-105.1686 Visualize the wind rose constructed for the specified location.
Raw time series https://dw-tap.nrel.gov/ts?height=35.00m&lat=39.7412&lon=-105.1686 Less user-friendly interface that allows external computational tools, dashboards, etc. access TAP's wind data.
Bias-corrected wind speeds(NEW) https://dw-tap.nrel.gov/bc?height=35.00m&lat=39.7412&lon=-105.1686&year=2011 Apply bias correction using observational data and show monthly average wind speeds, with and without bias correction.
Estimate kWh production(NEW) https://dw-tap.nrel.gov/kwh?height=35.00m&lat=39.7412&lon=-105.1686&year=2011&pc=nrel-reference-100kW Use the specified power curve to estimate kWh production over the specified period of time.
