Rapporteur Note by Jesse Meng

Review of the BAMS article planning.
- Xiquan Dong (U. of North Dakota) will contribute a side bar for Reanalyses compared with observations.
- Suru Saha (NCEP/EMC) will coordinate a list of EMC co-authors to contribute a section of coupled reanalysis development at EMC.

Xiquan Dong et al., Diagnosing and quantifying uncertainties of the reanalyzed clouds, precipitation and radiation budgets over the Arctic and SGP using combined surface-satellite observations
- three of the components in this project are reported
- 1) Evaluation of MERRA-2 atmospheric temperature, water vapor, and ozone profiles over three climate regimes (nearly submitted to JGR) by Erica Dolinar
- 2) Quantifying the uncertainties of reanalyzed Arctic cloud and radiation properties using satellite-surface observations (submitted to Clim Dyn) by Yiyi Huang
- 3) Comparison of the GPCP 1DD Precipitation Product and NEXRAD Q2 Precipitation Estimates over the CONUS (accepted by J. Hydrometeo) by Wenjun Cui
- Mike Bosilovich commented Merra-2 tends to have too much reflected shortwave fluxes at surface and the top of atmosphere that has been documented in NASA tech report.
- Gil Compo asked to revisit the uncertainty of the referenced satellite estimates of shortwave radiation and land surface albedo in Greenland.

Michael Ek et al., Improving the Land Surface Components of the CFS Reanalysis
- updates of project components
- NCEP Global Land Data Assimilation System (GLDAS)
- NASA-NCEP Land Information System infrastructure
- system upgrades with new land data sets, precipitation forcing, snow data assimilation, river routing, and drought/flood monitor
- follow up with Xiquan Dong to evaluate land surface albedo in Greenland.

The Mike Ek et al would like to give a briefing for project "Improving the Land Surface Components of the CFS Reanalysis".

Thanks,

Mike and Jesse
