ST MEETING 20 June, Forecast for 21 June - DOY 172


Tim/Trish
1. Please tell what is NOT operational in next messages
2. Did you do a race track ?. Why staying 36hrs idle near Sagres?
Suggestion to steam to 37N 17W and return to SE of Sagres by Sunday
morning. This will connect ship with Tenerife through a common
trajectory for a few hours (= Lagrangian set up). If not possible now,
this is certainly the idea for the coming weeks.
3. How is ship traffic S of Sagres (disturbance for clearLAG?)
Ciao



ST meeting 0620 Friday

Meteo  outlook N+1, N+2
upper levels: westerly flow over the whole ACE-2 area, strongest in the north.
lower levels: low of984 over the British Islands with the clouds of the cold front 
expecting to reach Sagresin the morning hours. For the rest of the ACE-2 area we
expect the same conditions as today. the day after tomorrow at upper levels a 
ridge of high presure will move eastward over Azores increasing the subsidence
later on over the ACE-2 area. in lower levels the remains of the cold fron will 
move southwards increasing cloudiness, mainly in the northeasterly. we can 
expect winds from NE at 15kts.

Meteo  outlook N+3, N+4
upper levels: ridge of high pressure slightly east of Azores. Increasing subsidence
over ACE area, this will lower the inversion height as well as the cloud tops. 
Lower levels: high pressure of 1028hPa over Azores extending to north of Ib. 
Peninsula. giving over ACE area slightly stronger winds from NE (15-20kts). 
Clear skies over Sagres, clouds scattered to broken southwards and broken to 
overcast just north of Tenerife.

Today
1. CLEARCOLUMN Pelican/IZO flight NOT performed
2. PCAPS intercomparison on Merlin NOT performed
3. Test flight Dornier performed

Saturday
5. Clean over Sagres and Tenerife.
6. CLEARCOLUMN Mission (Task 1.3) with Pelican/IZO/NOAA14
7. PCAPS intercomparison on Merlin and/or reconfiguration for ACE2
 
Sunday
8. Clean over Sagres and Tenerife.
9. Sagres/ship intercomparison  

Monday-Tuesday
10. possibility of European pollution outbreak

General.
- pollution prediction for Sagres, in case trajectories passing the
Iberian 
coast  less accurate than thought. Are similarly sensitive as for
Tenerife
- Can the von Karman waves south of the islands be a natural laboratory 
for aerosol-cloud interaction studies ? TNS lidar and A/C can check
pollution 
levels
- Should we plan more chemistry measurements in dust layers ?
- What would a clean full LAGRANGIAN tell more than ASTEX 
and ACE-1?
