NASA POWER

NASA POWER (Prediction Of Worldwide Energy Resources) is a project at NASA's Langley Research Center that publishes gridded weather and solar data built from satellite observations and reanalysis models. Through ScholarMuse an agent can request a daily or monthly series for one latitude and longitude and get back a table of values with units and a count of missing periods.

ScholarMuse tools: get_weather_history. Each successful call uses credits.

Ask your agent

Get the daily maximum and minimum temperature at 35.01, 135.77 (Kyoto) from June to August 2023.
What was the monthly mean precipitation at -1.29, 36.82 (Nairobi) from 1990 to 2020?
Give me daily solar radiation and wind speed at my field site, 52.52 N 13.40 E, for all of 2022.

What your agent gets back

Every record carries id, source, title, url, license, attribution and retrievedAt. The fields below are the data that comes from NASA POWER.

get_weather_history

One record per call. Each row in observations holds the date plus one value per requested variable (temperature_max, temperature_min, temperature_mean, precipitation, relative_humidity, wind_speed, solar_radiation).

location
Latitude, longitude and grid-cell elevation in metres (gridElevationM)
aggregate
daily or monthly
units
Unit of each variable as reported by POWER
powerParameters
POWER parameter code behind each variable, e.g. T2M_MAX
observations
Rows of date and values; missing values are null
count
Number of rows returned
periodsWithMissingValues
Rows where at least one variable is missing

What it covers

  • Any point on Earth by latitude and longitude, from 1981-01-01 up to today.
  • Seven variables: maximum, minimum and mean temperature, precipitation, relative humidity, wind speed and solar radiation.
  • Daily values, or monthly means for longer periods.

Limits

  • Start dates before 1981-01-01 and end dates in the future are rejected.
  • Daily data is limited to 2,000 days per call; longer ranges must use monthly means.
  • The values are gridded model and satellite estimates, not weather-station readings.
  • One point per call, and a request can take up to 40 seconds before it times out.

How ScholarMuse reaches NASA POWER

The connector calls the NASA POWER temporal API (daily or monthly point endpoint) at power.larc.nasa.gov with the Agroclimatology (AG) community setting. No API key is sent.

Responses are cached for up to 3 days, so the most recent days of a series can lag NASA POWER by that long.

API key: the upstream API can be called without one, so you do not add one.

Licence and attribution

Licence: Open data (NASA Earth Science data policy); acknowledgement requested

The data was obtained from the National Aeronautics and Space Administration (NASA) Langley Research Center's Prediction Of Worldwide Energy Resources (POWER) project funded through the NASA Earth Science Division.

Records that come from NASA POWER carry this licence and attribution. When you cite the data in a paper, follow NASA POWER's own citation guidance.

FAQ

ScholarMuse is not an official NASA POWER product. It is one MCP server for academic data, and its get_weather_history tool queries NASA POWER. An agent connected to ScholarMuse can use NASA POWER without a separate server.

No. The NASA POWER API can be called without a key, and ScholarMuse does not ask you for one. You sign in to ScholarMuse once and your agent calls the tool.

Yes. Each successful call to get_weather_history uses credits, and a call that fails is not charged. Current price: Historical weather data for any place, 1 credit / call.
