Abstract
Folland and Parker (1995) proposed the correction (so-called bucket correct ion) to historical sea surface temperature (SST) data from ship reports suc h as the Comprehensive Ocean-Atmosphere Data Set (COADS). In order to exami ne the validation of this correction, comparison is made between SST data a nd long-term coastal SST (CSST) data taken at nine stations around Japan. F or this purpose, we extract SST data in the adjacent areas surrounding nine CSST stations, from the files of GOADS and the Kobe Collection data which have been recently released by the Japan Meteorological Agency and the Japa n Weather Association. As a result, it is found that the data of five CSST stations among nine stations are suitable for comparison. When Folland and Parker's correction is adopted to the historical SST data, the systematic b iases in monthly mean SST anomalies have been corrected almost perfectly at three stations, and the biases at the other two stations have been reduced by 40-50 %.
