With the exception of bitlock, the spacecraft continues to perform nominally. As of Tuesday, July 14, we have gone 12 days without bitlock. The next group of special command loads is ready and awaiting bitlock to be sent to the spacecraft. The next CIPS Noon Flatfields will happen July 27 if they can be loaded.
SOFIE continues to operate nominally. Processing of the latest PMC season data has continued with no serious issues or lost of data though a minor software patch was needed because of event timing issues. The development of the next version of the retrieval software is also continuing with progress on both refraction T/P retrievals and the retrieval of CO2 mixing ratio profiles.
The SOFIE refraction measurement paper has been revised based on reviewer comments and is being prepared for re-submission. Reviews of the SOFIE meteoric smoke paper were received and the paper is being revised. Presentation were made at the AIM science team meeting, PMC workshop, and LPMR meeting: 1) AIM CV, 2) AIM hemispheric difference objective, 3) Ice refractive index, 4) SOFIE PMC particle property retrievals, 5) SOFIE meteoric smoke results.
CIPS continues to operate nominally, and is measuring many clouds in this 2009 northern hemisphere season. We are currently updating the software with which we plot the “daily daisies” that give an initial qualitative picture of where the clouds appear each day; the improved software should result in more easily viewed clouds. Because of a spacecraft command error, the flat field images that were to be acquired in late June were unsuccessful. Thus we are re-processing all of the NH 2009 data with flat fields that were acquired in May 2009. Because of a transition to autonomy mode, these observations were not complete, but they are an improvement over using the NH 2008 flat field data. We are attempting to upload commands for a new set of NH 2009 flat fields. We are continuing to evaluate a new level 4 retrieval algorithm based on an optimal estimation approach; preliminary results indicate significant improvements over the operational retrieval with regard to deriving the particle radius.
