Monthly solar radiation and weather for 34 localities, 1981-2025 (NASA POWER)

NASA POWERMonthly1981 – 202534 locationsSatellite or reanalysisCC BY 4.0

Monthly means of the same parameters as the NASA POWER daily series, over the full depth available from the producer.

Same start dates per parameter: weather from 1981, global and diffuse radiation from 1984, direct radiation, clearness index and albedo from 2001.

Coverage by measure

Years with values for each measure; not all of them start at the same time at the producer.
