Significant AMDAR Problems During Period

Identifier Description Status/Date EADAS1 down and all data rerouted through 09/01/04 – 12/01/04 EADAS2 since 1005UTC All data between 06:46-10:18 was queued. Data flowed wef 10:20 with data being 20/01/2004 mirrored to EADAS2. Webserver replication programme also restarted. Interruption of the BUFR IUAg01 EGRR transmission from 03:03 to 10:21 UTC. The 22/01/04 transmission of IUAX01 EDZW was undisturbed in both cases. Interruption of BUFR EGRR of data(EGRR -> EDZW) 03:01 UTC - 06:33 UTC. No problem at the EGRR FROST end 29/01/04 E-ADAS and no outages at Offenbach for the times in question. Interruption of the transmission 18/02/2004 (EGRR -> EDZW03:02 UTC - 06:18 UTC). ADAS: No data has been received for "30" minutes from Eadas1 Investigated and the system is operating 01/03/2004 correctly. The warning message was triggered by a genuine lack of AMDAR observations due to flight scheduling. No Lufthansa data processed 08:50 UTC – 15:23 UTC. Due to the circuit from FROST not being migrated.. 04/03/2004 Data feed switched back from EADAS2. There should be no affect on data to the GTS. Fault of the Lido central database from 24th 05:00 to 25th 05:00 UTC and from 25th Jan 20:00 UTC to 26th 10:00 UTC, but E-ADOS 24/01/04 – 26/01/04 needs some hours to run "round" again. BUFR data transmitted only sporadically during this period. EADOS shows 28th and no data available for th E-ADOS 29 . Lido had problems with the receipt of the OBS data. These data are the basis for the E-ADOS optimization. The consequence was sub-hourly profiles. 01/04/2004 Other important note: On 28th Feb (10:07 - 20:20 UTC) and 29th Feb (16:29 - 20:27 UTC) was again an interruption of the transmission EGRR to EDZW. The Met Office external internet services were disrupted between 08:00 - 11:05. This was caused by a "break" in the routing to the Met Office. This prevented E-ADAS from receiving data over the ARINC ftp service. All data was ARINC 23/01/2004 stored on the Met Office server at ARINC. Once Internet services were restored, queued data was processed and inserted on the GTS. Lufthansa data processed as this is routed separately. On one occasion, 17th Dec, both EUCOS and KNMI stats reported a daily bias of >9deg. However, the Meteo France December 2003 monitoring at Toulouse indicates that EU 8736 undergoes a temperature bias between 1 and > 2°C. On this occasion, it 27/01/04 - is agreed that EU8736 be deactivated until after the next maintenance period.

Transport (Trade Union recruiting among others also technical ground staff at airports) has announced strike actions directed towards , , SAS Commuter, 28/01/04 - Blue 1 and Snowflake on Friday and Monday mornings. Negotiations between SAS and Transport on going

OPERATIONAL REPORT British Airways implementation of the compressed software on the B737 fleet has been further delayed by staff resource shortage at BA - data costs for the short haul fleets Ongoing continues to be monitored closely The problem with ftp transfer to the EADAS WebServer continues (update to monthly Ongoing graphs etc) The system developer and TC are working on resolving this issue. UAL has increased the number of aircraft reporting EDR. Most of these additional reports, however, include only EDR, not wind and temperature. 25/03/2004

Saudi Data on GTS:Data exchange on the GTS stopped suddenly because the agreement between the airline and PME is awaiting signature. All transmissions from the aircraft have been switched off until this approval. The airline is also upgrading the 31/03/2004 software and aircraft configurations as quickly as possible. A new operational trial is due to commence just as soon as the agreement is signed. A strike by French air traffic controllers caused the mass cancellation of flights at Orly 16/02/2004 Airport south of . Significant Network Developments During Period Description Status/Date New Lufthansa AMDAR aircraft:EU6148 A340-600 27/01/04 SAAB Aircraft: Development of a service bulletin for implementation of TAMDAR on January 2004 SAAB 340 aircraft. The work is made on behalf of the TAMDAR manufacturer AirDat LCC. SAS B767 – some units still temporarily active. Reduced tariff agreed with SAS until January 2004 complete phase out of this fleet A cost summary regarding AMDAR data from BA aircraft sent to Hong Kong January 2004 Observatory. Delay in development of Air France long haul aircraft is having a “knock-on” effect on January 2004 the planned provision of data to ASECNA. PM has raised this issue with the WMO AMDAR Panel. SAS aircraft EU6113 A330 added to the fleet 10/02/2004 LH aircraft EU6188 A340-600 added to the fleet 16/02/2004 First AMDAR data from Saudi Arabia appeared on the GTS.

Sealand Motivator (WAAH) 24 TEMPs had been transmitted to the GTS. January 2004 Problems with the GPS antenna on SL MOTIVATOR could be solved by the E- ASAP Project Team during her call in Bremerhaven CanMar Pride (ZCBP6) Arrived in Hamburg was provided with 17/01/04 Helium by the E-ASAP Project Team. The crew was informed to start the launchings on time to avoid timelags in the bulletin header. Reissue Fault report 82: Frequently reports below the agreed target of 90% of all data achieving 100hPa height, and has recently dipped below the agreed target of 75% of all data achieving 50hPa height. Action on Fault report 82:Visit to Hamburg. 08/02/2004 Protection rubber installed round the Launcher door to save the ballons as they were bursting on the hard edge. Note:Canmar Pride uses RS80-15G sondes, but RS92 maybe introduced from July 2004.

Action on Fault 82:There have been several 17/10/2003 times when the pre-flight ground control corrections have been outside their tolerances. PMO visited the Canmar Pride in Antwerp on 17th October 2003 and discussed this problem with the crew. The CanMar Pride has recently changed to 17/03/04 the summer launching schedule. However, they will shortly resume three observations daily as they did in the winter half including St. Lawrence Seaway, to meet the 2004 ASAP programme observation target. Sealand Performance (KRPD) Communication problems: A faulty antenna Resolved February 2004 was replaced and a new software version was installed by a Vaisala engineer.

OPERATIONAL REPORT * (1) 9 EUCOS sites frequently launch >2 radiosondes /day, (2) 5 EUCOS sites frequently launch <2 radiosondes/ day. (3)** Timeliness used for EUCOS sonde statistics is measured by subtracting the nominal ascent time from the time of receipt. 'nominal ascent time' is defined as a multiple of 3 hours (HH) such that the launch time lies between HH -2 and HH +1. For example, any launch between 10Z and 13Z would have a nominal time of 12Z.

Significant Network Developments During Period Date LUT of Sondre Stromfjord has been connected to Service Argos since mid-February. In practice, the raw Argos data received at Sondre Stromfjord are sent to CLS/Argos through FTP and then processed in Toulouse before GTS transmission as the raw data coming from other receiving stations. 01/03/2004

No future drifting buoy data are sent onto the GTS from Sondre Stromfjord.

# Statistics provided by E-SURFMAR *only ten EUCOS moored buoys out of the twelve are operating ** This target corresponds to 40 buoys reporting 90% of hourly data, it replaces a target which was "24 obs/buoy/day".It is in agreement with the present monthly figures and those of other components.
