Coastal Facility for Atmospheric Research (CFAR) NREL site Purpose : Operational testing of NRL-MRY's atmospheric instrument suites prior to deployment. Long-term measurements in a coastal marine environment for model validation. Reference 'standards' for validation and calibration of field instruments. CFAR Rooftop Observation Deck ‘First Light’ on 29Dec2013

CFAR Lidar Profiling of Asian Dust Instrument will become polarization-sensitive in FY15 Still, without depolarization, dust scattering is very distinct in lidar measurements
Aerosol/Cloud Airborne Measurement Capability CIRPAS Twin Otter Utilization of CIRPAS Aircraft * Run by NPS in partnership with Cal Tech * Full complement of instrumentation to support atmospheric and oceanographic research: - Met: T, P, RH, dropsondes - Cloud/Aerosol: size, concentration, composition - Radiation (in development): up and downwelling solar/IR flux, AOD Eliminates one of the biggest sources of error and the most time-consuming data reduction step in airborne radiometer measurements Platform level to within +/- 0.02 deg Development of Stabilized Platform/Radiometer Package
Navy Aerosol Analysis and Prediction System (NAAPS) The U.S. Navy Aerosol Analysis and Prediction System (NAAPS) is an operational global aerosol transport model used to forecast visibility conditions for fleet operations and motivate basic research. 6-day forecasts every 6 hours of global sulfate, SO 2, dust, smoke and sea-salt mass concentrations. Grid:.33°x.33° degree; 25 sigma levels to 100 mb http://www.nrlmry.navy.mil/aerosol

International Cooperative for Aerosol Prediction: Formalizing the Aerosol Prediction Community After an initial 2010 Monterey meeting, aerosol forecast system developers meet annually under the ICAP umbrella. Developers do not officially speak for their lab or make commitments, but rather gather discuss problems and best practices. ICAP allows developers to speak as a community and make scientific recommendations. “Ticket to Ride” is a global aerosol model running at least quasi operationally or a global satellite data provider. Current model members: BSC, ECMWF, JMA, NASA GMAO, NOAA NCEP, NRL, UKMO ICAP has made significant headway in convincing international agencies to expend resources on aerosol forecasting problems.
