On rerun and replacement of GODAS pentad data for August 2018 to March 2019 For years, WMO has worked for transition data format from TESAC to BUFR in GTS. In the efforts, Argo data in the NCEP tank also has been change to BUFR format since July 2018. Accorng to this data format change of Argo, GODAS data decoder was updated following the change. It has been known that there were issues in the updated decoder, and occures warm bias in upper layer of GODAS (e.g. 0-110 m depth), which is due to the incorrect conversion. From reruns of updated codes, following data are replaced godas.P.20180823.grb godas.P.20180828.grb godas.P.20180902.grb godas.P.20180907.grb godas.P.20180912.grb godas.P.20180917.grb godas.P.20180922.grb godas.P.20180927.grb godas.P.20181002.grb godas.P.20181007.grb godas.P.20181012.grb godas.P.20181017.grb godas.P.20181022.grb godas.P.20181027.grb godas.P.20181101.grb godas.P.20181106.grb godas.P.20181111.grb godas.P.20181116.grb godas.P.20181121.grb godas.P.20181126.grb godas.P.20181201.grb godas.P.20181206.grb godas.P.20181211.grb godas.P.20181216.grb godas.P.20181221.grb godas.P.20181226.grb godas.P.20181231.grb godas.P.20190105.grb godas.P.20190110.grb godas.P.20190115.grb godas.P.20190120.grb godas.P.20190125.grb godas.P.20190130.grb godas.P.20190204.grb godas.P.20190209.grb godas.P.20190214.grb godas.P.20190219.grb godas.P.20190224.grb godas.P.20190301.grb godas.P.20190306.grb godas.P.20190311.grb godas.P.20190316.grb godas.P.20190321.grb godas.P.20190326.grb godas.P.20190331.grb godas.P.20190405.grb godas.P.20190410.grb godas.P.20190415.grb April 30th 2019 Hyun-Chul Lee (hyun-chul.lee@noaa.gov)
