  1. RIHMI-WDC and CDIAC Climate Data Activities Dale Kaiser Carbon Dioxide Information Analysis Center* & Climate Change Science Institute Environmental Sciences Division Oak Ridge National Laboratory *CDIAC is funded by DOE’s Climate Change Research Division, Office of Biological and Environmental Research kaiserdp@ornl.gov http://cdiac.ornl.gov http:/climatechangescience.ornl.gov

  2. RIHMI-WDC Climate Data on the CDIAC Website

  3. RIHMI-WDC Climate Data on the CDIAC Website

  4. NDP-048 3- and 6-hourly surface variables (Updated in 2007 with data through 2000)

  5. 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?

  14. 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 Changes in cloudiness and related variables over Russia, 1950–2000 Garrett P. Marino (MIT) and Dale P. Kaiser (ORNL – CDIAC) 22 January 2008

  15. Daytime Total Cloud Cover Changes in cloudiness and related variables over Russia, 1950–2000 Garrett P. Marino (MIT) and Dale P. Kaiser (ORNL – CDIAC) 22 January 2008

  16. Daytime cloudiness Trends in occurrence of: Occurrence of daytime cumulus clouds Daytime cumulus clouds Daytime stratus clouds Changes in cloudiness and related variables over Russia, 1950–2000, Marino and Kaiser, 20th Conference on Climate Variability and Change, New Orleans, LA, January 2008
