It is expected to be updated on a monthly time schedule and may not always be current.
This page contains links (buttons to the left) to the following:
-
Global conventional observation monitoring This site provides time series, histograms, horizontal maps, and vertical profiles of O-A and O-B for each conventional data type for each global analysis cycle, it also show the data number assimilated, rejected in GSI various quality control procedures
-
Global conventional station monitoring - This site provides time series, horizontal maps, vertical profiles and histograms of O-B and O-A statistics (mean and standard deviation) for each conventional observation station of each data type from global analysis over a certain period.
-
Regional conventional station monitoring - This site provides time series, horizontal maps, vertical profiles and histograms of O-B and O-A statistics (mean and standard deviation) for each conventional observation station of each data type from regional analysis over a certain period.
