7. 7Managed by UT-Battelle for the Department of Energy Potential Future Data Exchange and Data Access via CDIAC Website Sterin upper-air temperature anomaly time series (updated) Russian daily temperature and precipitation updates (subset of 223 former-USSR stations; any additional variables?) Does the GHCN Daily dataset supersede RIHMI data? Russian 3- and 6-hourly updates (>20 variables) Make daily and/or 3- and 6-hourly Russian surface data available through a CDIAC USHCN-style interface? RIHMI data should have more QA than raw(?) data on NCDC site. (NCDC already has powerful GIS station data interface.) Joint RIHMI-WDC/CDIAC Russian surface-data analysis and publications?

Kaiser (ORNL – CDIAC) 22 January 2008  Past studies [e.g., Sun and Groisman (Int. J. Clim. 2000), Sun et. al. (J. Climate 2001)] investigated cloud trends using prior versions of NDP-048 database. Their findings:  Decrease in low-level cloud cover (St)  Increase in Cu clouds  Increase in total cloud cover
