Summary of Revisions (in reverse order)
Revision 28 (June 18) - Monitoring of SYNOP and SYNOP-SHIPs now includes BUFR encodedobservations for those which were assimilated as well asfor those without TAC counterpart.
Revision 27 (Mar 13) - Monitoring of Radiosondes and ASAPs now includes BUFR encodedobservations for those which were assimilated as well asfor those without TAC counterpart.Tables 24 and 25 are also added to show the identifiers ofthese BUFR observations separately.
Revision 26 (Feb 15) - Selection criteria for SHIPs are modified as perSOT-7/Doc.9.1.1.Different criteria applied to Manual and Automatic SHIPs.
Revision 25 (Dec 14) - Coverage chart for ATOVS AMSU-A for Noaa_16 removed
Revision 24 (Aug 06) - North Atlantic Monitoring statistics replaced byEUCOS Area Monitoring Statistics (tables 13 to 23).Airep tables removed from this section.
Revision 23 (Dec 00) - Coverage charts for Noaa_14 MSU replaced byATOVS AMSU-A for Noaa_16.
Revision 22 (Aug 99) - Coverage charts for TOVS thickness 300-100hPa replaced by (A)TOVS AMSU-A and MSU(Noaa_15 and Noaa_14).
Revision 21 (May 99) - Monitoring statistics ceased for Noaa_11 assatellite is no more available.
Revision 20 (Sep 98) - Changes to tables and annex to remove allmention about data usage. Two more levels(50 and 850 hPa) added to the COSNA statisticsfor Sondes.
Revision 19 (Jul 98) - From June 29th, 1998 ECMWF model assimilatestemperature data instead of geopotential fromradiosondes. As a consequence the number ofused geopotential data drops to zero in tables7, 10, 13 and 15.
Revision 18 (Apr 98) - Changes to tables and annex to introduce theusage of accepted numbers and observationsinstead of precentage of rejection.
Global Data Monitoring Report
1 INTRODUCTION 3
1 Introduction
The ECMWF global data monitoring report is a monthly publication intended to give an overview of theavailability and quality of observations from the Global Observing System within the World Weather Watchof the World Meteorological Organisation. It should be recognised that the statistics given in this report referto data as received at ECMWF in time for the appropriate analysis. The annex of the report gives furtherexplanations of the methods applied to compile the statistics and on the reference used to establish the qualityof observations.
The information presented on data quality is based on differences between observations and the values ofthe most recent ECMWF forecast (”first guess”) of the same parameter. Depending on the time of theobservation, the forecast range is between 9 and 15 hours. It should be recognised that although the qualityof the first-guess is of a generally high standard this is only true to a limited extent in certain areas, such asthe tropics and data-sparse areas of both northern and southern hemispheres. The data quality results shouldtherefore be used with care when assessing the absolute quality of a particular observing platform. Otherindicators such as long-term trends of station performance, particularly in comparison with nearby stations,can be more useful in this respect.
The global monitoring results presented in this report are meant to serve a wider meteorological communityas well as to support special WMO programmes such as TOGA and EUCOS. The contents of the report maytherefore be adapted for special requirements as necessary.
As recommended at the ninth session of the Commission for Basic Systems at Geneva 1988, lead centres havebeen appointed for each main type of observation which should liaise with the participating centres and co-ordinate all the results, inform the WMO Secretariat immediately of obvious problems, and produce every sixmonths a consolidated list of observations of that particular type believed to be of low quality. The presentlynominated centres are: RSMC Exeter for marine surface observations; RSMC ECMWF for radiosonde andpilot observations; WMC Washington for aircraft and satellite observations.
ECMWF produces this monthly report as part of its routine monitoring activity in order to facilitate theexchange of monitoring information. Tables are presented according to the CBS recommended standards forthe exchange of monitoring results. Copies of the report will be provided to major GDPS centres participatingin data monitoring activities as initiated and recommended at the ninth session of the Commission for BasicSystems in Geneva 1988, and to the WMO Secretariat and the International TOGA office in Geneva.
Any comments on the contents and the format of the report are welcome and should be addressed to:

5 Annex - Explanations of figures and tables
5.1 General
All information presented in this report is based on data received at ECMWF before the appropriate analysis.Approximate cut-off times (UTC) are shown below:
Analysis Obs Time Cut-off
0000 2101-0300 1530 (16 hours)1200 0901-1500 1900 ( 7 hours)
5.2 Data Availability
For each observation type/parameter the average number of reports received per day is displayed in boxes of5 degrees square. The numbers plotted are the nearest integer values - e.g. if 40 reports were received duringthe month then the average daily value plotted will be 1. If the average number is greater than 1000 then999 will be plotted. If the average number is less than 0.5 then the digit 0 will be plotted. If no observationswere received then the box will be left blank.
5.3 Data Quality
The information presented on data quality is based on differences between observations and the values ofthe most recent ECMWF forecast (”first guess”) of the same parameter. Depending on the time of theobservation, the forecast range is between 9 and 15 hours. The ability of a modern data assimilation systemto provide the diagnostic facilities to monitor the performance of the observational network is demonstratedby A. Hollingsworth et. al., Monthly Weather Review, Vol 114, No. 5, May 1986.
It should be noted that:
(i) all results are based on software that may undergo further development;
(ii) although the quality of the ECMWF first-guess fields is of a generallyhigh standard this is only true to a limited extent in the tropics,where small-scale processes such as convection are of much greaterimportance than in mid-latitudes, and the observations will sometimesnot be representative of the scales of motion given by the first-guess;
(iii) the first-guess fields themselves will vary in accuracy depending on thedensity and quality of data, particularly in the upstream regions andover Antarctica and the southern hemisphere mid-latitudes. Directcomparisons between stations (or airlines) should preferably be restrictedto observations in a reasonably homogeneous climatic region.
Tables 1-9 contain lists of SHIPs (including fixed marine platforms), DRIFTERs, TEMPs and TEMPs/PILOTsbelieved to have supplied suspect reports of surface pressure, geopotential height or wind during the month.The format of the tables is according to Recommendation 3 CBS-Ext(85) and the criteria for stations or dataplatforms to be classified as suspect are given at the top of each table. For tables 7 and 8 data for the worst

standard pressure level are shown. Units of RMS, standard deviation and bias are hPa in tables 1 and 4, min table 7 and ms−1 in tables 2, 5 and 8. In tables 7 and 8 the station position is indicated; in the case ofTEMPSHIPs and PILOTSHIPs this position is obtained from the first report of the month. The gross errorlimits for first-guess deviations of geopotential in table 7 are as follows:

Tables 10 and 11 provide geopotential and wind quality statistics (100 hPa level) for TEMPSHIPs and PI-LOTSHIPs received during the month. Units and display format are identical to those in tables 7 and 8respectively. Tables 13, 14 (50 hPa), 15 and 16 (100 hPa), 17 and 18 (500hPa), 19 and 20 (850hPa) providesimilar radiosonde statistics for the EUCOS area.
Tables 21-23 are similar to tables 4-6 with data coverage restricted to the EUCOS area.
Figures 14-18 show global charts of SATOB and aircraft wind quality, where the statistics have been averagedover latitude/longitude boxes of 5 degrees square, and the mean observed minus first-guess (or ’bias’) windvectors have been plotted. All observations in the specified layers have been used. For comparison the meanobserved wind (from the SATOB reports only) for each layer is shown in figures 14 and 15. A referencevalue of wind speed is plotted in the top right corner of each figure. An arrow is only plotted if 10 or moreobservations have been received in that 5 degree square.
Table 12 provides quality statistics of aircraft wind observations in the layer 300-150 hPa stratified by airlinecarrier. The format and specifications of the table have been defined by NMC Washington, the lead centrefor the monitoring of aircraft and satellite data.
Table 24 shows list of Assimilated BUFR Encoded Radiosonde Stations monitored within the month.
