Jens,
Since you like cloud bows and Rich showed me some really nice HSRL2 data for this day, I attached an image from RSP on 7/28 over Monterey Bay when there was smoke above the clouds. The data and quick looks from RSP are at http://data.giss.nasa.gov/pub/rsp/ORACLES_2016/ The bright yellow at 18.90 UTC with a green polarized reflectance is thick smoke. The polarized reflectance is green because RGB is 2260, 865 and 410. Smoke is Rayleigh like at 865 nm and very strongly polarizing, almost transparent at 2260 nm and reduces the polarized reflectance at 410 by masking molecular scattering. Hence, smoke is bright green :)

Hi Jens,
The striping in some of the DOLP images is an artifact of the onboard processor that generates these quicklooks. Typically as a flight progresses the assumptions the processor makes about the photoelastic modulator parameters become less accurate due to temperature drift. This is to minimize the amount of real-time calculations. It is not an issue for ground data processing, so the final images do not have these artifacts.

Very neat. Thanks for sharing, Felix. Looks like all the ER-2 instrumenters are extremely proactive in sharing their quick-look imagery, which I appreciate a lot. I really like the cloud bows in the DOLP images. Incidentally, what causes the striping in some of the DOLP images? If it is too technical, feel free to postpone explanation until we are in Namibia.
Cheers,
Jens

Hi Rich
Technically, AirMSPI should be ready the next day for a science flight, but we would prefer a day in the lab to check the instrument and data after the long transit flight.
Please find attached an overview of AirMSPI data acquired on Aug 3. Shown are quicklooks of Level 0 (raw) data.
I will send the same overview, but for the test flight on July 28 in a separate email.
Thanks,
Felix

Hi Jeff,
Thanks for the information. Also, thanks for the images; I think this was an interesting flight.
Please find attached a powerpoint that shows some of the HSRL-2 data acquired during this flight. There was a nice range of aerosol loading and aerosol types observed. HSRL-2 also measured smoke properties from Soberanes fire.
It would be interesting to combine the various datasets to investigate the aerosol and cloud properties.

EMAS may take two or even three full days after arrival to be ready for flight. It will all depend on the status of the vacuum in the COB (Cold Optical Bench.) We have never done three consecutive long flights without pumping before, so the vacuum will have to re-established, and then it takes about 8 hours to get back to operating temperature (~77K.)
FYI, Attached is an EMAS image pair from the last test flight, over the Soberanes fire (Natural color & SWIT/LWIR composites.)

ER-2 instrument folks,
It would also be helpful to know how soon after the ER-2 arrives in Namibia would your instrument be ready for a science flight (next day, two days, etc.?) and if there any special conditions that need to be met for this to happen.
Thanks,
Rich

That's terrific. Thanks, Sam.
ER-2 instrumenters,
if you could update your instrument status in the appropriate tab of the google doc linked below, I would greatly appreciate it. This will help our team communication tremendously, I believe.
Thanks in advance for your efforts to keep this information up to date,
Jens

Jens, other instrumenters,
I went ahead and changed the spreadsheet to include a tab for the ER2 and a separate tab to split out the status of the cloud probes and the HiGEAR instrument suites. Please find below a link that will allow you to edit the document.

Thank you.

Thanks so much, Sam.
Congratulations to the P-3 crew and instrumenters on a job very well done. There were some significant hurdles and you cleared them beautifully. I absolutely love the instrument status tab on the google docs spreadsheet. That will likely be the way we will move forward with instrument status summaries. Would it be OK, if we added a tab for the ER-2 instrument status as well and renamed the doc ORACLES aircraft summaries or something like it? Or should we start a separate google doc for that?
Thanks again to all involved with the P-3 for getting us to this point.

Hello all,
We have just landed from the 2nd P3 test flight. It went well; we got almost all objectives. The clear air was less clear than hoped and forecasted, but there was some useable periods. The cloudy portion near Wallops was less cloudy than hoped, but still got some good short cloud penetrations with some small droplets. We did get low flying over ocean, with a couple of ship plume interceptions. Almost all instruments worked well including PDI, CCN did not, neither did CAPS from the cloud probes, and TDMA from the HiGEAR rack. HiGEAR did find more leaks than they had hoped.
A summary from the flight can be found here:
