Monthly Subsurface Temperatures in the Pacific Ocean Term: from January 1981 to latest Area: 59.5S - 69.5N, 90.5E - 60.5W, 1 degree x 1 degree Method: objective analysis using in-situ observation Explanation: They are estimated by an objective analysis using in-situ subsurface temperatures observed by research vessels, buoys and so on (Kimura et al., 2010). Data Format: One data file consists of 525 records, one header record and 524 data records. The header record contains the year and month in four digits each from the left. The grid point values (GPVs) at a depth of 50m are stored on a 131-record block from 2nd record, those at a depth of 100m on the next block from 133rd record, those at a depth of 200m on the 3rd block from 264th record, and those at a depth of 400m on the last block from 395th record. The depth information is stored in three digits on the first record of each 131-record block. The GPVs on the grids along 69.5N are stored on the 2nd record of the block, those along 68.5N are on the 3rd record of the block, and those along 59.5S are on the 131st record of the block. Each record contains the 210 GPVs from 90.5E to 60.5W at the interval of 1 degree in longitude. Each GPV domains four digits in the unit of 0.01 degree Celsius. The GPV is 9999, if the temperature is not determined or the grid point is below the bottom of the ocean. References: Kimura, M., W. Ito and T.
