Saylor Innovations Data Desk – NASA POWER Daily Weather

Choose this endpoint when you need historical daily weather data for any arbitrary geographic coordinate worldwide — especially remote locations without traditional weather station coverage. It is ideal for agricultural, energy, environmental, or construction analysis where NASA POWER's satellite-derived gridded data provides better global coverage than station-based services. Prefer this over forecast APIs when you need past observations, and over general weather APIs when you need solar radiation data or need coordinates far from urban weather stations.

• Missing required lat or lon parameters returns a validation error
• Date range exceeding 61 days may be rejected or truncated
• Invalid coordinate values (outside -90 to 90 lat or -180 to 180 lon) return an error
• NASA POWER upstream unavailability may cause timeouts or empty responses
• Requesting dates beyond the available NASA POWER dataset (very recent days not yet processed) may return null or partial data
