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.

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:

2.1 Radiosondes

The following is a list of land-based stations showing a change in reporting frequency (of 500 hPa geopotential)of at least 10 observations compared with the average over the previous 3 months. The number of reportsreceived at ECMWF for the current and previous month is shown in addition to the observation time.

Surface pressure observations from 1504 drifting buoys were received during the month.

3 Global monitoring statistics

The following figures and tables provide information on both the availability and quality of various data typesas received at ECMWF during the month. A brief description of each figure/table is given below. For a fullexplanation please refer to the Annex.

3.1 Data Availability

Figures 1-9 are global charts for each data type showing the average number of observations received in 24hours in 5 degree boxes. The average daily number of observations (global) is also displayed with a breakdown,where appropriate, for each WMO region (figures 1, 3 and 4) and Ocean (figures 1-4).
