Reynolds-Smith V2 global monthly average sea surface temperatures

From the parent record held in the GCMD:The data sets in the CDC archive called "Reynolds SST' and "Reconstructed Reynolds SST" were discontinued on 1 April 2003.A new OI SST data set is available as described here, which includes a new analysis for the historical data and updates into the future. NCEP will not provide new data for the "Reynolds SST" after December 2002 and CDC will remove the "Reynolds SST" data set on 1 April 2003.TO SEE THE NEW DATASET, PLEASE SEARCH THE GLOBAL CHANGE MASTER DIRECTORY FOR MORE INFORMATION. REFER TO THE METADATA RECORD (LINKED BELOW): REYNOLDS_SST#############This metadata record is a modified child record of an original parent record registered at the Global Change Master Directory. (The Entry ID of the parent record is REYNOLDS_SST, and can be found on the GCMD website - see the provided URL). The data described here are a subset of the original dataset. This metadata record has been created for the express use of Australian Government Antarctic Division employees. Reproduced from: http://www.emc.ncep.noaa.gov/research/cmb/sst_analysis/Analysis Description and Recent ReanalysisThe optimum interpolation (OI) sea surface temperature (SST) analysis is produced weekly on a one-degree grid. The analysis uses in situ and satellite SSTs plus SSTs simulated by sea ice cover. Before the analysis is computed, the satellite data are adjusted for biases using the method of Reynolds (1988) and Reynolds and Marsico (1993). A description of the OI analysis can be found in Reynolds and Smith (1994). The bias correction improves the large scale accuracy of the OI.In November 2001, the OI fields were recomputed for late 1981 onward. The new version will be referred to as OI.v2.The most significant change for the OI.v2 is the improved simulation of SST obs from sea ice data following a technique developed at the UK Met Office. This change has reduced biases in the OI SST at higher latitudes. Also, the update and extension of COADS has provided us with improved ship data coverage through 1997, reducing the residual satellite biases in otherwise data sparse regions.The data are available in the following formats:Net CDFFlat binary filesText

最优插值海表温度（OI SST）分析产品以每周为周期生成，分辨率为1度网格。该分析融合了原位观测海表温度、卫星反演海表温度以及海冰覆盖模拟的海表温度数据。在开展分析计算前，研究人员将采用Reynolds（1988）与Reynolds和Marsico（1993）提出的方法对卫星数据进行偏差校正。关于OI分析方法的详细说明可参阅Reynolds和Smith（1994）的研究，偏差校正可提升OI分析的大尺度精度。
2001年11月，研究人员对1981年末至今的OI场数据进行了重新计算，新版本被命名为OI.v2。
OI.v2最显著的改进在于，依据英国气象局开发的方法优化了海冰数据模拟的海表温度观测值，此举有效降低了高纬度地区OI SST产品的偏差。此外，海洋与大气协作数据集（Cooperative Ocean/Atmosphere Data Set, COADS）的更新与扩展提升了截至1997年的船舶观测数据覆盖范围，进一步降低了数据稀疏区域残留的卫星观测偏差。
该数据集支持以下获取格式：网络通用数据格式（NetCDF）、二进制平面文件以及文本格式。
