The Campaign
The Amazonian Aerosol Characterization Experiment (AMAZE-08) was a NASA field investigation focused on the formation, transformations, and cloud-forming properties of biogenic aerosol particles, as well as their impact on cloud activation and climate. AMAZE-08 consisted of a single deployment from February to March 2008 during the wet season in the central Amazon Basin. Ground-based measurements of aerosols, trace gases, clouds, and meteorological parameters were collected at tower and field sites. Additional measurements were collected at an AErosol RObotic NETwork (AERONET) site. AMAZE-08 was supported by NASA, the National Science Foundation (NSF), the Brazil LBA Millennium Institute, the Max Planck Society, the Brazil Large-Scale Biosphere Atmospheric Experiment, and the European Integrated Project on Aerosol Cloud Climate and Air Quality Interactions (EUCAARI).

The AErosol RObotic NETwork (AERONET) is a federated network of ground-based remote sensing aerosol sensors established in 1993 by NASA and the PHOtométrie pour le Traitement Opérationnel de Normalisation Satellitaire (PHOTONS). Each AERONET site includes a CIMEL Electronique sunphotometer that measures solar irradiance and sky radiances. These measurements are used to determine aerosol properties, including aerosol optical depth and extinction. The sunphotometers operate at nine wavelengths (340, 380, 440, 500, 675, 870, 937, 1020, and 1640 nm) and provide aerosol data approximately every 15 minutes. AERONET sites are distributed worldwide, enabling mapping of about 90% of the Earth’s surface.

Condensation Particle Counters (CPCs) are in situ sensors that measure aerosol particle concentrations. CPCs determine aerosol concentrations by condensing a fluid onto particles, causing them to grow to sizes detectable by optical scattering. Typically, CPCs detect particles from 7 nm to 3 μm, measure concentrations up to 100,000 particles per cubic centimeter, and provide readings every second. CPCs are manufactured by TSI Incorporated and can be used on airborne, shipborne, and ground-based platforms.
