Observations Monitoring of the Canadian Centre for Meteorological and Environmental Prediction (CCMEP), Meteorological Service of Canada

Introduction

The next sections contain statistics on the availability and quality of meteorological observations used in CMC final global analyses, such as aircraft, AMVs, ATOVS, GeoRad, IASI and SSMIS radiances, scatterometer and profilers winds, GPSRO, radiosondes and surface observations. Inside each section are the following parts:

• Data Reception includes the information about the number of decoded observations and their distribution. Files include data until T+7 hours.
• Data Quality Monitoring based on a comparison with the first guess, includes information on the quality of observations before thinning.
• Data included in Analysis includes information about the number of observations assimilated by the CMC operational analysis, their distribution and time series of the mean and standard deviation of values of observation minus first guess (O-P) and observation minus analysis (O-A).

In each part described above, figures are separated according to a color legend:
