• Data assimilation: integrated forecast and analysis of observations
• Goal: high quality atmospheric data sets for research
• Size of data sets and computational requirements: very large
• fvGCM and PSAS components successfully parallelized
• Data management components - Observer, I/O, Couplers - now bottleneck
• Library frameworks important for data management parallelization
