Dakar

Ouagadougou

Niamey

? D/F20 Niamey ? Geophysica (M55) Dakar ?

M55 – 3 local flights funded and 1 from CNES, but relying on EUFAR funding – decision end April.

Hangar renovation v. expensive so now local AMMA rep negotiating.

If Ouaga is a NoGo – Niamey is not an alternative

Dakar could be revisited (logistically and scientifically) but time is short.

Visit to Oauga in April – involving Jan.

If Geophysica does not go to Ouaga, can D/F20 go to Niamey ? Same number of aircraft as in SOP2a1 for military hangar– but people (15) / offices may be a problem.

ATR – some EMC checks and test flying of instruments has taken place – continuing through April and May

Permission to fly only below 10,000ft, and not in turbulence.F/F20 – EMC tests in progress.

Chemistry to be installed and test through April, then role change for first AMMA deployment.

Communication with scientists on Falcon. Currently the only way is through the pilots.

Communication with ATC in W. Africa during SOP0 was often difficult.

F/F20, ATR, D/F20, M55, 146

T = time that MSC is in target area – Niamey or Djougou regionsTake off timesF/F20 T-2h – 1 flightM55 T-2h – 1 flightD/F20 T-1h – 1 flight (focus on anvil)ATR and 146 – 2 flights: 1 before and 1 after the MCS

Do we need both the 146 and ATR to fly before and after ?ATR limited to day light flying –so only 146 if darkPrefer daylight for photochemistry and DjougouATR will need 3 flights and refuel at Niamtougou for DjougouNeed to create some time lines for different times of T.

146 will try to combine these flights with I1.4

SOP2-a2I3.1: Impact of MCSs on TTL composition

D/F20, M55

Similar to I2 but looking at outflow further away from the MCSs

If possible D/F20 and M55 would target outflow from an MCS that had picked up air from an area sampled by other aircraft on a previous day.

SOP2-a2I3.2: Large scale impacts of deep convection on LRT

F/F20, D/F20, M55, 146

Large scale outflow in between MCSs

146 will focus on mid level flow (AEJ)Other aircraft at higher altitudes

N-S transects

Aim to fly on the same day along the same meridianor parallel displaced by longitude
