The Campaign
The Carbonaceous Aerosol and Radiative Effects Study (CARES) was a field campaign that examined the evolution and characteristics of secondary organic aerosols (SOA) and black carbon (BC) to help improve climate chemistry models. CARES involved a single deployment in California's Central Valley in June 2010. The Department of Energy (DOE) G-1 and NASA B-200 aircraft gathered both in situ and remote-sensing data on aerosols and trace gases. Ground-based measurements were also collected at a site within the Sacramento urban source area and at a receptor site downwind. CARES was primarily funded by the DOE, with NASA serving as a significant participant, supporting the deployment of the B-200 aircraft.

The High Spectral Resolution Lidar (HSRL) is an airborne lidar system developed at NASA Langley Research Center (LaRC). It uses the HSRL technique at 532 nm and the standard backscatter technique at 1064 nm to provide profile measurements of aerosol backscatter, extinction, and depolarization. The profiles of aerosol backscatter and depolarization typically have a vertical resolution of 30 m and a horizontal resolution of about 1 km. For the extinction profiles, the vertical resolution is 300 m with a horizontal resolution of approximately 6 km. HSRL is usually flown during investigations to validate observations from the CALIPSO spaceborne lidar.

Digital cameras are used to provide imagery for research applications. Cameras are used on aircraft to collect aerial imagery for mapping and surveying, environmental monitoring, cloud observations, agriculture, geological studies, and other Earth science applications. They are also used at field sites to capture visual observations to monitor changes in land cover, vegetation, clouds, air quality, glaciers, and other phenomena.

Radiosondes are a balloon-borne instrument package used to collect profile measurements of pressure, temperature, humidity, and winds. These sensors are connected to a radio transmitter that sends the measurements to a ground receiver typically operating in the 400-406 MHz range. They typically provide measurements at 1-6 seconds, depending on the type and manufacturer of the radiosonde. Radiosondes are used for weather forecasting, ground truth satellite data, atmospheric research, and input for weather prediction models.
