Daily maps for global daylight length at 30 arc seconds resolution (2022)

Overview:

Daily maps for global daylight length, calculated for the year 2022.


Processing steps:

For each day within the year 2022, the photoperiod (sunshine hours on flat terrain) are calculated using the SOLPOS algorithm developed by the National Renewable Energy Laboratory (NREL), USA. Resultant values have been converted from hours to minutes.


File naming scheme (DDD = day within year) (min is abbreviation for minute):

daylight_min_2022_DDD.tif


Projection + EPSG code:

Latitude-Longitude/WGS84 (EPSG: 4326)


Spatial extent:

north: 90

south: -90

west: -180

east: 180


Spatial resolution:

30 arc seconds (approx. 1000 m)


Temporal resolution:

Daily


Pixel values:

unit: minutes


Software used:

GDAL 3.2.2 and GRASS GIS 8.2.0
