[Oracles-er2-investigators] ER-2 test flight

[Seidel, Felix (398E)]

Hi Rich, Armin

Caltech & JPL’s ImPACT-PM mission performed coordinated flights with the ER-2 and CIRPAS’s Twin Otter about two weeks ago. It went very well. Marko (CIRPAS pilot), Tim, Stu, and Greg (NASA ER-2 pilots) were involved. They are up to speed in case you want to do something similar next week. I can also offer my help, if you want.

From an AirMSPI standpoint, we would be VERY excited to get cloud droplet size distribution data from CIRPAS sampled near the cloud top (within the cloud, but the sun should be still visible a little bit). This would give us unique validation data for AirMSPI cloud droplet size retrievals, which we currently developing for ORACLES. It would also be very useful for RSP and others, I’d guess.

PS: James, thanks for making the connection.

Thanks,
Felix

Hi Armin, James, et al.

We had a very good flight yesterday which obviously saw lots of smoke over Monterey and downwind.  We also did get some cloud measurements over Monterey Bay from HSRL-2 and the polarimeters. The HSRL2 also found some smoke over these clouds.

Our next (and probably final) test flight will either be Tuesday or Wednesday, depending on instrument readiness.  The attached charts and files indicate the initial thoughts on this test flight. The pattern includes segments over land calibration and AERONET sites for instruments to check performance since this is a test flight.  The instruments also want to fly over the ocean (and clouds over ocean) so this pattern includes a segment over the ocean off of San Francisco. This particular over water leg is at a specific orientation to optimize polarimeter performance and avoid glint.

The area off the coast is outside the warning areas so hopefully the Twin Otter can fly here also.  The ER-2 pattern is limited in duration since we are trying to conserve hours for the ORACLES science flights from Namibia.

I have cc’ed the ORACLES ER-2 investigators so they are aware of this potential opportunity.

Forgot to answer the last question…yes, we will be flying many more flights over the course of the next two weeks. Will most likely be doing a long leg tomorrow up the coast outside of the ADIZ towards the CA/OR border before returning back to Monterey. We will do sawtooth patterns from near surface below cloud bases up to a few hundred feet above tops and keep repeating that for many hours.

Rich,

Thanks for the heads up!  A colleague from Univ. Arizona, Armin Sorooshian, is conducting Twin Otter flights this week in/out of CIRPAS in Marina.  I recognize that aerosol/smoke are likely the primary focus of your observational strategy, but Armin is doing cloud chemical sampling within the marine layer.  I wonder if there may not be some means for collaboration between his in-situ measurements near cloud top and perhaps some of your retrievals (eMAS, HSRL-2, RSP, in particular).

Armin is cc’d….you watch, they’ll be in a down day today…LOL…I trust you guys are flying a few more days over the next week or so, though?  Armin?

best, jc
