From source to product signal

Test a product idea in four steps

POWER serves analysis-ready solar and meteorological estimates for selected coordinates. Start with one point, two parameters, and one month. Values represent model or satellite grid cells rather than a site sensor, latency differs by parameter, and recent meteorology is later quality-replaced.

1

Check the setup

  • Python 3.10 or newer
  • A notebook environment such as Jupyter or Google Colab
  • A longitude and latitude for the location being tested
2

Access the data

  1. 1.Use the parameter dictionary to confirm names, units, source, and temporal availability.
  2. 2.Request one point, no more than two parameters, and a one-month daily period.
  3. 3.Record coordinate, time standard, spatial resolution, and retrieval date with the response.

Run the Python example

Install the packages, then run the notebook cell.

python -m pip install pandas requests

import pandas as pd
import requests

response = requests.get(
    "https://power.larc.nasa.gov/api/temporal/daily/point",
    params={
        "parameters": "T2M,ALLSKY_SFC_SW_DWN",
        "community": "RE",
        "longitude": -112.074,
        "latitude": 33.4484,
        "start": "20250701",
        "end": "20250731",
        "format": "JSON",
        "time-standard": "UTC",
    },
    timeout=30,
)
response.raise_for_status()
daily = pd.DataFrame(response.json()["properties"]["parameter"])
daily.index = pd.to_datetime(daily.index)
print(daily.head())

Test a useful signal

Profile daily solar resource at one location

Compare daily solar radiation and temperature for Phoenix during July 2025.

  1. 01Confirm parameter units and retrieve one month for a single coordinate in UTC.
  2. 02Plot daily solar radiation and temperature and flag missing values.
  3. 03Explain how grid resolution, modeled values, latency, and later quality replacement limit site decisions.
