The Coupling Between Tropical Meteorology, Aerosol Lifecycle, Convection, and Radiation during the Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex)

Abstract

The NASA Cloud, Aerosol, and Monsoon Processes Philippines Experiment (CAMP2Ex) employed the NASA P-3, Stratton Park Engineering Company (SPEC) Learjet 35, and a host of satellites and surface sensors to characterize the coupling of aerosol processes, cloud physics, and atmospheric radiation within the Maritime Continent’s complex southwest monsoonal environment. Conducted in the late summer of 2019 from Luzon Philippines in conjunction with the Office of Naval Research Propagation of Intraseasonal Tropical OscillatioNs (PISTON) experiment with its R/V Sally Ride stationed in the North Western Tropical Pacific, CAMP2Ex documented diverse biomass burning, industrial and natural aerosol populations and their interactions with small to congestus convection. The 2019 season exhibited El Nino and associated drought, high biomass burning emissions, and an early monsoon transition allowing for observation of pristine to massively polluted environments as they advected through intricate diurnal mesoscale and radiative environments into the monsoonal trough. CAMP2Ex’s preliminary results indicate 1) increasing aerosol loadings tend to invigorate congestus convection in height and increase liquid water paths; 2) lidar, polarimetry, and geostationary Advanced Himawari Imager remote sensing sensors have skill in quantifying diverse aerosol and cloud properties and their interaction; and 3) high resolution remote sensing technologies are able to greatly improve our ability to evaluate the radiation budget in complex cloud systems. Through the development of innovative informatics technologies, CAMP2Ex provides a benchmark dataset of an environment of extremes for the study of aerosol, cloud and radiation processes as well as a crucible for the design of future observing systems.

How Variable Are Cold Pools?

“…Case‐study simulations with 1 km horizontal grid spacing are performed using the Regional Atmospheric Modeling System (RAMS; Cotton et al., 2003; Saleeby & van den Heever, 2013) for the NASA Cloud, Aerosol, and Monsoon Processes Philippines Experiment (CAMP 2 Ex; Reid et al., 2023, S.3.2). Includes a coarse and high‐resolution simulation of a cold pool that occurred west of Luzon (simulation CS‐TropOce‐1km; Text S1 in Supporting Information ; and CS‐TropOce‐100m; Text S1 in Supporting Information ; Figure 1c).…”

An Airborne Multifrequency Microwave Analysis of Precipitation within Two Winter Cyclones

“…AMPR has been used in past field campaigns including the Olympic Mountains Experiment (OLYMPEX) (Houze et al 2017) and the Cloud, Aerosol, and Monsoon Processes, Philippines Experiment (CAMP 2 Ex) (Reid et al 2023). Previous work with AMPR imagery has explored the ability to detect and distinguish various microphysical environments or dominant precipitation types within cloud and precipitation structures using all four channels in concert.…”
