Or a ground temperature can be chosen according to a TRY region, which is listed below: if ...
TRY_Region == 1 then 282.15 K
TRY_Region == 2 then 281.55 K
TRY_Region == 3 then 281.65 K
TRY_Region == 4 then 282.65 K
TRY_Region == 5 then 281.25 K
TRY_Region == 6 then 279.95 K
TRY_Region == 7 then 281.95 K
TRY_Region == 8 then 279.95 K
TRY_Region == 9 then 281.05 K
TRY_Region == 10 then 276.15 K
TRY_Region == 11 then 279.45 K
TRY_Region == 12 then 283.35 K
TRY_Region == 13 then 281.05 K
TRY_Region == 14 then 281.05 K
TRY_Region == 15 then 279.95 K
