Monthly mean solar and meteorological parameters for 54 world cities from NASA's POWER API (sources: SYN1deg, MERRA-2), January 1981 to the current month: air temperature, precipitation, relative humidity, wind, surface pressure, and surface solar irradiance / PAR. Long-run climate-trend companion to the daily dataset.

Schema

Column	Type	Description
date	string	Observation date from the POWER API response keys. Daily temporal keys are YYYYMMDD; monthly temporal keys are YYYYMM, stored as the first day of that month.
city	string	Name of the world city the point location represents (curated by the connector; not part of the POWER API response).
country	string	Country of the world city (curated by the connector; not part of the POWER API response).
latitude	float	Latitude of the requested POWER point in decimal degrees (curated by the connector). (unit: decimal degrees)
longitude	float	Longitude of the requested POWER point in decimal degrees (curated by the connector). (unit: decimal degrees)
t2m	float	Temperature at 2 Meters — POWER API parameter T2M (community RE). (unit: C)
t2m_max	float	Temperature at 2 Meters Maximum — POWER API parameter T2M_MAX (community RE). (unit: C)
t2m_min	float	Temperature at 2 Meters Minimum — POWER API parameter T2M_MIN (community RE). (unit: C)
prectotcorr	float	Precipitation Corrected — POWER API parameter PRECTOTCORR (community RE). (unit: mm/day)
rh2m	float	Relative Humidity at 2 Meters — POWER API parameter RH2M (community RE). (unit: %)
ws10m	float	Wind Speed at 10 Meters — POWER API parameter WS10M (community RE). (unit: m/s)
ps	float	Surface Pressure — POWER API parameter PS (community RE). (unit: kPa)
allsky_sfc_sw_dwn	float	All Sky Surface Shortwave Downward Irradiance — POWER API parameter ALLSKY_SFC_SW_DWN (community RE). (unit: kW-hr/m^2/day)
clrsky_sfc_sw_dwn	float	Clear Sky Surface Shortwave Downward Irradiance — POWER API parameter CLRSKY_SFC_SW_DWN (community RE). (unit: kW-hr/m^2/day)
allsky_sfc_par_tot	float	All Sky Surface Total PAR — POWER API parameter ALLSKY_SFC_PAR_TOT (community RE). (unit: kW-hr/m^2/day)
ws50m	float	Wind Speed at 50 Meters — POWER API parameter WS50M (community RE). (unit: m/s)
wd50m	float	Wind Direction at 50 Meters — POWER API parameter WD50M (community RE). (unit: Degrees)
