Introducion of AphroClim: Daily climatological mean gridded temperature dataset based on surface observation

Abstract

A daily mean gridded temperature dataset of monsoon Asia (15S-55N, 60E-150E) for the period of 1961-2007 is created and open to public (Yasutomi et al., 2011) as a part of APHRODITE project(Yatagai et al., 2012). The number of stations used the interpolation analysis is up to 2 times the number of stations based on the Global Telecommunication System (GTS), which have been used to obtain other gridded temperature products. We obtained daily surface observation in collabollation with the local agency.
I introduce characteristics of its climatology and impact of increasing observations in Tibet and Himalaya region.
