ACEPOL Forecast Support


The ACEPOL (Aerosol Characterization from Polarimeter and Lidar) campaign ACEPOL ER-2 instrumentationwill perform aerosol measurements over the USA from the NASA high altitude ER-2 aircraft using measurements of 4 different spectro/photo polarimeters (RSP, airMSPI, airHARP and airSPEX), which differ in terms of spectral, angular, and spatial sampling. These passive measurements will be complemented by active measurements from airborne HSRL-2 and CPL lidars and a number of ground sites.

This campaign will assess the capabilities of the different polarimeters for retrieval of aerosol microphysical and optical parameters, as well as their capabilities to derive aerosol layer height (near-UV polarimetry, O2 a-band). This work provides insight into the information content of future active and passive aerosol sensors being considered by the ACE per-formulation study, and it is equally relevant to other missions such as METOP-SG, Earthcare and PACE.
