Processed Datasets used for the Cirrus Impacts on PBL Height analysis during the CAMP2Ex Weather and CompoSition Monitoring campaign in 2019 over Manila Observatory, Philippines

The Cloud, Aerosol, and Monsoon Processes Philippines Experiment (CAMP2Ex) Weather and Composition Monitoring (CHECSM) campaign offered an exceptional platform for examining how tropical cirrus influences boundary‑layer conditions in an urban region (Reid et al., 2023). The dataset draws on coordinated observations from advanced, collocated instruments, including a ground‑based High Spectral Resolution Lidar (HSRL) and an SPN1 pyranometer operated at the Manila Observatory (MO; 14.64°N, 121.08°E), Philippines, spanning January 2019 through June 2020. We also include here Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) variables extracted over the study site. (Gelaro et al., 2017) In this folder you will find: ahsrl_20191002T2055_20191003T1155_60s_30m.nc: HSRL data for October 3, 2019. HSRL data is also available for download here. spn1_pyranometer_manilaobservatory_5min_2019.csv: SPN1 pyranometer 5-minute irradiance quantities for 2019 . 2019_cirrus_v2025.csv: HSRL 5-minute retrievals of cirrus cloud optical and physical properties for dry days and days with less than 50% low cloud cover in 2019 2019_cirrus_v2025_no50clfilter.csv: HSRL 5-minute retrievel cirrus cloud optical and physical properties for dry days in 2019. pblh_hsrl.zip: HSRL 1-minute retrievals of mixed layer height which we also call PBL height in the manuscript. merra2_surface.csv: Extracted MERRA-2 hourly, time-averaged land surface sensilble heat flux and net shortwave for gridpoint over Manila Observatory, Philippines from MERRA2_400.tavg1_2d_lnd_Nx files.
