Description
About the
NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) mission, launched in April 2006 and operational until 2023, provided 17 years of valuable data. Its primary payload, the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), was an elastic backscatter lidar transmitting polarized laser light at 532 and 1064 nm. CALIOP measured range-resolved backscatter intensities, enabling the detection of clouds, aerosols, and surface features. Building on CALIPSO’s legacy, the Earth Clouds, Aerosols and Radiation Explorer (EarthCARE) mission and the planned Cloud-Aerosol Lidar for Global Observations of the Ocean-Land-Atmosphere (CALIGOLA) mission represent the next generation of lidar-based atmospheric research. EarthCARE, led by ESA and JAXA, features the Atmospheric Lidar (ATLID) operating at 355 nm. Meanwhile, CALIGOLA will deploy a three-wavelength system (355, 532, and 1064 nm) with rotational Raman channels to enhance measurement capabilities.
Traditionally, the data processing for space lidar measurements has relied on physics-based approaches. However, machine learning (ML) is increasingly being utilized in Earth science applications due to its advanced architectures, computational efficiency, and the availability of high-performance resources. ML has become invaluable for processing and analyzing large volumes of Earth observation datasets.
This opportunity focuses on developing ML-assisted retrievals of aerosols in the planetary boundary layer, emphasizing aerosol and cloud detection and classification using multichannel measurements at the highest spatial resolution. The extensive 17-year CALIOP archive provides an ideal training dataset for ML algorithms, enabling their adaptation to EarthCARE’s ATLID and the future CALIGOLA mission. This research aims to generate a multi-year dataset of boundary layer aerosol properties, enhancing our understanding of aerosol-cloud interactions and their impact on climate processes.
