Here we offer a unique climatology of the land surface temperature derived from the annual cycle in MODIS land surface temperature (LST) data. The main motivation for such a climatology is the fact that daily land surface temperature maps usually have plenty of gaps due to cloud coverage. The climatology provided here allows computing the climatologic mean land surface temperature for a particular day of the year without data gaps due to clouds for the entire globe.
This is done with the following equation:
LST(day) = MAST + YAST * SIN(day * 2 pi/365 + Theta)
where LST is the land surface temperature to be retrieved for day day, MAST is the mean annual land surface temperature for 2003-2014, YAST is the mean annual amplitude of the land surface temperature for 2003-2014, and Theta is the phase shift in days relative to spring equinox on the northern hemisphere (see parameters). Note that day is counted relative to spring equinox on the northern hemisphere as well, e.g. March 31: day = 10.
The parameters were derived based on collection 005 of the MODIS daily level 3 global 1 km grid product from EOS Terra and Aqua (MOD11A1 and MYD11A1) - separately for night time and for day time.
