The EarthCARE lidar cloud and aerosol profile processor (A-PRO): the A-AER, A-EBD, A-TC and A-ICE products

David Patrick Donovan, Gerd-Jan van Zadelhoff, and Ping Wang

Abstract. ATLID (“ATmospheric LIDar”) is the lidar to be flown on the multi-instrument Earth Clouds and Radiation Explorer (EarthCARE). EarthCARE is a joint ESA/JAXA mission now scheduled for launch in 2024. ATLID is a 3 channel linearly polarized High-Spectral Resolution (HSRL) system operating at 355 nm. Cloud and aerosol optical properties are key EarthCARE products. This paper will provide an overview of the ATLID L2a (i.e. single instrument) retrieval algorithms being developed and implemented in order to derive cloud and aerosol optical properties. The L2a lidar algorithms that retrieve the aerosol and cloud optical property profiles and classify the detected targets are grouped together in the so-called A-PRO (ATLID-profile) processor. The A-PRO processor produces the ATLID L2a Aerosol product (A-AER), the Extinction, Backscatter and Depolarization product (A-EBD), the ATLID L2a Target Classification (A-TC), and the ATLID L2a Ice microphysical estimation product (A-ICE). This paper provides and overview of the processor and its component algorithms.

This manuscript provides a detailed overview of aerosol and cloud products to be expected from the upcoming EarthCARE mission. In documenting the basic steps of processing of the data from the ATLID instrument it will be a very valuable source of information for users of the resulting products.
Short summary
ATLID (“ATmospheric LIDar”) is the lidar to be flown on the Earth Clouds and Radiation Explorer satellite (EarthCARE). EarthCARE is a joint European-Japanese satellite mission scheduled for launch in 2024. ATLID is an advanced type of lidar optimized for cloud and aerosol profile measurements. ATLID will provide novel measurements, and thus, novel methods for inferring aerosol and cloud profiles have been developed. This paper provides an overview of these novel retrieval methods.
