Carbon Monoxide Blooms September 2005

Carbon Monoxide Blooms September 2005

AIRS’ global carbon monoxide measurements are important because scientists can monitor the transport of fire emissions around the globe on a daily basis. Previously, carbon monoxide measurements came from satellite instruments that saw only part of the Earth each day or from weather balloons. Prior to AIRS, scientists had to integrate those observations with computer models to infer the day-to-day impact of fire emissions on the atmosphere. AIRS provides daily, global coverage. AIRS also measures some of the key atmospheric gases that affect climate, including ozone, methane, and dust and other aerosols.

Tropospheric CO abundances are retrieved from the 4.67 m region of AIRS spectra as one of the last steps of the AIRS team algorithm. AIRS’ 1600 km cross-track swath and cloud-clearing retrieval capabilities provide daily global CO maps over approximately 70% of the Earth.

The streak of red, orange, and yellow across South America, Africa, and the Atlantic Ocean in this animation points to high levels of carbon monoxide, as measured by the Atmospheric Infrared Sounder (AIRS) instrument flying on NASA’s Aqua satellite. The carbon monoxide primarily comes from fires burning in the Amazon basin, with some additional contribution from fires in southern Africa. The animation shows carbon monoxide transport sweeping east throughout August, September, and October 2005.

Cassini instrument test lab

Cassini instrument test lab

In a clean room in the basement of JPL’s Space Flight Operations Facility, working copies of the Cassini instruments remain at the ready to compare with signals from the spacecraft. This allows engineers to test responses of new commands on the instruments, but also to troubleshoot anomalies.

In this photo, Stefan Helfert from Germany stands by the working copy of the Cosmic Dust Analyzer (CDA). It looks like a tin can, but it has the capability of capturing dust particles and ions and analyzing them with a mass spectrometer. As with all the instruments, measurements must be digitized, sent to the onboard computer and packetized for transmission to Earth. CDA gathered valuable data about Titan, Enceladus and the Saturn space environment during Cassini’s tour.

CDA is one of the half-dozen instruments that will be working during Cassini’s descent into Saturn in a few hours. Along with a few other instruments, any measurements of Saturn’s atmosphere will be ricocheted to the antenna to send back every last bit of data possible before the spacecraft vaporizes when it hits the atmosphere at 77,000 mph.

Because I worked with members of the ITL team, I took this picture on a private tour my coworkers and I got of the clean room in September, 2005. We had to vacuum our clothes, then don special slippers, caps and coats to enter this restricted space. This room is off limits to the public; indeed, most members of the Cassini team have never been in here.

If you can, watch the final moments of Cassini on NASA TV or Space.com, starting at 4:00 a.m. PDT on Friday, 9/15/17.
