The Campaign
The Joint Airborne IASI Validation Experiment (JAIVEx) was a multi-agency field investigation sponsored by NASA, the UK Met Office, NOAA, and other organizations. Its primary goal was to collect radiance measurements to validate and calibrate satellite data from NPOESS and MetOp. JAIVEx involved one deployment at Ellington Field in Houston, TX, during the boreal spring of 2017. The NASA WB-57 aircraft was equipped with the NPOESS Aircraft Sounder Testbed-Interferometer (NAST-I), NPOESS Aircraft Sounder Testbed-Microwave (NAST-M), and Scanning High-resolution Interferometer Sounder (S-HIS) to gather radiance measurements for validation. Ground-based observations were obtained from the Department of Energy (DoE) Atmospheric Radiation Measurement (ARM) program’s Cloud and Radiation Testbed (CART) research site in the southern Great Plains.

The Shortwave Spectroradiometer (SWS) is a radiometer that measures absolute visible and near-infrared spectral radiance. It includes two Zeiss spectroradiometers to measure spectral radiance, which are used to determine cloud optical depth, particle size, and water path. One spectroradiometer operates in the 300-1100 nm wavelength range at a spectral resolution of 8 nm, while the other operates in the 900-2200 nm range at a resolution of 12 nm. SWS has a sampling frequency of 1 Hz. The Department of Energy’s Atmospheric Radiation Measurement (ARM) User Facility operated a ground-based SWS, and the Facility for Airborne Atmospheric Measurements (FAAM) operated an airborne version as part of the airborne laboratory.

Dropsondes, also known as dropwindsondes, are in situ instruments designed to be released from aircraft. They are equipped with Global Positioning System (GPS) receivers and sensors to collect profile measurements of pressure, temperature, humidity, wind speed, and wind direction. Dropsondes are important during field investigations because they enable researchers to collect vertical profiles in remote locations and during severe weather conditions. Typically, dropsondes have a vertical resolution of 5 meters and provide wind speed and direction measurements every 0.25 seconds, while temperature, pressure, and humidity are recorded every 0.5 seconds.

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.
