The setting environment is indicated by a classification number: 1 for inside the observation site of the local meteorological office; 2 for inside the grounds of a local district/commune/police office; 3 for inside the garden of a private house; 4 for on a roof over a private house; and 5 for inside a paddy field. The measuring resolution is 0.5, 0.2, and 1.0 mm for gauge types A, B, and C, respectively. The gauge height is from the ground surface to the top of the receiving orifice. Five stations with the symbol “–” are excluded from the analysis due to frequent missing data
