In Summer 2004 several coordinated experiments will study air quality, intercontinental transport, and radiation balance in air masses carried across the US and over the Atlantic to Europe. NASA is organizing INTEX-NA. NOAA is organizing NEAQS - ITCT 2004. And Europeans are organizing ITOP. ICARTT was formed to enhance the synergy between INTEX, and ITOP.
AATS-14 will participate in INTEX and ITCT by flying on a twin turboprop Jetstream-31, based at Portsmouth, NH in July and August 2004. Its goal is to help characterize aerosol radiative properties and effects in flights that sample polluted and clean air masses in coordination with measurements by other INTEX-ITCT platforms, including aircraft and a ship.
|The primary purpose of this experiment is to validate the over-ocean MODIS aerosol optical depth (AOD) measurements at 1.6 and 2.1mm aboard the Terra and Aqua platform. The primary tool for validating the MODIS AOD is the 14-channel NASA Ames Airborne Tracking Sunphotometer, AATS-14, which will fly aboard the CIRPAS Twin-Otter aircraft out of Monterey, CA. The timing of the experiment is chosen to coincide with the maximum transport of Asian dust to the US West coast, one of the few aerosol species with considerable AOD in the near-IR.|
To gain improved understanding and model-based representation of aerosol radiative influences an IOP is planned to be conducted at the Department of Energy's ARM Southern Great Plains Site in north central Oklahoma, in May 2003. The planned IOP will carry out a variety of closure experiments on aerosol optical properties and their radiative influence. Additionally, planned measurements of the aerosol chemical composition size distribution will allow testing of the ability to reconstruct optical properties from these measurements.
|The Asian Dust Above Monterey-2003 (ADAM-2003) project is a surface and airborne observational field study to investigate the properties and effects of the natural and anthropogenic Asian aerosols transported to the west coast of the United States in the springtime. ADAM-2003 will take place from April 1-30, 2003 based out of the Monterey, CA. AATS-14 will be operating onboard the CIRPAS Twin Otter.|
The SAGE III Ozone Loss and Validation Experiment (SOLVE II) is a measurement campaign designed to examine the processes controlling ozone levels at mid- to high latitudes. Measurements will be made in the Arctic high-latitude region in winter using the NASA DC-8 aircraft, as well as balloon platforms and ground-based instruments. The mission will also acquire correlative data needed to validate the Stratospheric Aerosol and Gas Experiment (SAGE) III satellite measurements that will be used to quantitatively assess high-latitude ozone loss.
CLAMS is an aircraft field campaign running from July 10 through August 3, 2001. It is a shortwave closure experiment targeting clear (cloud-free) sky conditions. Our AATS-14 instrument will be integrated on the CV-580.
The first major airborne/shipborne campaign of ACE-Asia took place in March-April 2001. Both of our instruments, AATS-14 and AATS-6, were involved in the experiment. AATS-14 was integrated on the CIRPAS Twin Otter. AATS-6 flew on the NCAR C-130. Both planes were flown out of Iwakuni Marine Corps Air Station, Japan.
