SUMMARY REPORT ON THE MONITORING OF ASAP SHIP DATA
January-December 2007
1. Summary: The number of reports received at ECMWF were slightly reduced compared to 2006, the percentage of ascents reaching 100 hPa back to normal values between 90 and 95%. The main problems were related to wrongly located reports particularly from January to June 2006. Apart from that the statistics show a good general performance of the ASAP units. 2. Data reception: Time series showing the ASAP data reception at ECMWF since January 1994 can be seen in figures 1 to 3.

Temperature 500 hPa - GLOBALMonthly counts of ASAP received at ECMWF
00 UTC 12 UTC 06 UTC 18 UTC
Figure 1
ASAP temperature data received at ECMWF 500 hPa (January 1994 to December 2007) The global number of reports in 2007 was similar to 2006 as shown in figure 1. The level of 500 hPa is a good indication of the total number of reports since the percentage of ascents reaching that level is close to 100 %. Detailed figures of the reception in 2006 and 2007 can be found also in tables 1 and 2. The global number of reports was slightly reduced in 2007 compared to 2006 as shown in the tables. When looking to the lower stratosphere the percentage of ascents reaching 100 hPa are back to the values of 2005 between 90 and 95 % as shown in figure 2.

Figure 3
ASAP temperature data received at 20 hPa Jan 1994 to Dec 2007 (all cycles together) The amount of data received at 20 hPa is still increasing. In the summer of 2007 we received the largest amount of data ever from ASAP platforms as shown in figure 3. The coverage area covered by the ASAP units is mostly the North Atlantic and areas close to Japan. Sometimes ASAP operating in the South Atlantic, South Indian, Mediterranean and Black sea can be found. The

Caribbean is a regular destination for several French ASAP, the Spanish ASAP operates south of the Canary Islands and a few reports were available

ASAP coverage January to December 2007
in the tropical Pacific. Figure 4 shows a summary of the operating ASAP in 2007. 3. Troubleshooting: The main problem in 2007 was a significant number of reports wrongly located particularly for the period January to June. A good number of the wrongly located reports can be spotted either visually in a coverage chart as the one shown in figure 4 or using an automatic tracker which will get easily ships travelling at unrealistic speeds (see table 3). But there are occasions when a wrong location will skip a filter like that. Several cases of that kind took place in 2007 involving mainly to the Danish ASAP units. For example in January 2007 21% of the reports of ASAP OXTS2 were bad positioned and 56% in February. Another Danish ASAP with Id OXGN2 got 32%, 23% and 29% of wrong positions in February, March and April 2007. In most of the cases the error was due to a change in the longitude sign but in 23 occasions between February and April 2007 OXGN2 reported as positioned in port close to Copenhagen when actually was sailing in the North Atlantic. A detailed list of bad positions in 2007 can be found in table 3. The problem with the Danish ASAP was the reason why they were blacklisted at ECMWF for several months until the problem was fixed at the end of April 2007. Since then we still see one or two cases every month but far away from the high percentages seen the first four months of 2007. As an

Figure 5
ASAP tracks in December 2007 example in figure 5 ASAP tracks for December 2007 shows ASAP ASDK01 which changed twice the latitude sign from North to South Hemisphere. The number of corrupted call-signs looks larger in 2007 compared to 2006. Tables 1 and 2 contain detailed figures with the reports received at ECMWF in 2006 and 2007. 4. ASAP data monitoring at ECMWF: The monitoring tools at ECMWF have been updated and refined to deal with reporting issues and data quality both in the daily monitoring and longer time scales namely monthly biannual and annual. Figures 6 to 10 the time series used to monitor the quality of conventional data can be found. We compute and update these time series on a daily basis for different parameters and atmospheric layers. Figure 6 is for used data above 400 hPa and it does not show relevant changes in the trends. The average differences OB-FG and OB-AN are small and the spread of the observations around the FG (vertical lines) is within normal limits. A more noisy structure can be seen for the layer 400-700 hPa shown in figure 7 but again both the biases and the spread are not bad. Figures 8 and 9 are for wind vector differences with FG and AN at two different atmospheric layers. Again the time series show a general good performance. It’s worth to note that in figures 6 to 10 only used data have been considered so the wrongly located reports are not part of this data set since most of them were rejected by the model quality control. The time series for humidity at mid tropospheric levels shows also good data quality.

Vertical statistics ASAP ASFR1 : Temperature, wind direction and speed

5. Conclusions:
• The number of ASAP reports received at ECMWF show a slight reduction in 2007 compared to 2006.
• The percentage of launches reaching the level of 100 hPa is back to values between 90 and 95% in 2007.
• Corrupted call-signs received from time to time. • The wrongly reported positions have been a major issue in 2007
particularly from January to June 2007. In most of the cases the reports were rejected by the model QC but in a few occasions passed though the model quality control. This problem has not been detected in any of the Japanese ASAP.
• The ASAP data are monitored at ECMWF using a number of products updated on a daily basis in our web site.
• The ASAP statistics have continued to show a good performance.
