The Campaign
The Observing-System Research and Predictability Experiment (THORPEX) Observing System Test (TOST) was a field study aimed at improving short- and long-range forecast products. TOST included two deployments in 2003: PTOST (Pacific) and ATOST (Atlantic). PTOST took place from February to March 2003 over the Pacific Ocean and the Hawaiian Islands. ATOST occurred from November to December 2003 over the Eastern United States and the Atlantic Ocean. The NASA ER-2 was equipped with multiple instruments, including the MODIS Airborne Simulator (MAS), to collect measurements of meteorological parameters and cloud properties. TOST was part of the THORPEX program.

The Airborne Vertical Atmospheric Profiling System (AVAPS) is an airborne system that uses dropsondes and Global Positioning System (GPS) receivers to gather in situ profiles of atmospheric parameters. It provides profile measurements of temperature, pressure, and humidity every 0.5 seconds, and atmospheric wind measurements every 0.25 seconds. AVAPS has a vertical resolution of approximately 10 meters and can launch dropsondes every 20 seconds. Developed by the National Center for Atmospheric Research (NCAR) for the NASA Global Hawk, it can also be deployed on other aircraft such as the DC-8 and P-3.

The NPOESS Aircraft Sounder Testbed - Microwave (NAST-M) is an airborne microwave radiometer operated by the Massachusetts Institute of Technology (MIT). It measures brightness temperature, which can be used to retrieve water vapor profiles in the atmosphere. It consists of two radiometers: one operating across eight channels between 50-57 GHz and the other across nine at 118 GHz. In 2003, NAST-M was upgraded with two additional radiometers at 183 and 425 GHz to enhance water vapor retrievals and detect small hydrometeors. NAST-M has a spatial resolution of 2.6 km and a cross-track swath width of 100 km at a flight altitude of 20 km. Its typical integration time is 100 ms.
