Time Information

Time Standards

POWER provides two different time standards for Hourly and Daily temporal level data:

  • Universal Time Coordinated (UTC): The most widely accepted standard for time measurement worldwide.
  • Local Solar Time (LST): A 15 Degrees swath that represents solar noon at the middle longitude of the swath.

POWER defaults to providing LST for Hourly and Daily temporal levels and provides UTC for other temporal levels. To change the time standard for Hourly or Daily, please include time-standard=UTC or time-standard=LST in the API request URL.

Time Range

  • POWER's time stamp represents the start of the hour for the whole hour.
