We present a new seasonal planetary boundary layer height (PBLH) climatology product derived from 14 years of Global Navigation Satellite System radio occultation (GNSS-RO) data multiple missions including COSMIC, TerraSAR-X, KOMPSAT-5, and PAZ. PBLH estimates are the minimum gradients retrieved refractivity profiles, with vertical resolution ∼200 m. The is obtained occultations observed between June 2006 December 2019, divided into land ocean regimes on 2-degree grid. provide climatologies at as well diurnal cycle amplitude phase 5-degree resolution. GNSS compared to radiosonde ship-based Marine ARM GPCI Investigation Clouds (MAGIC) campaign in subtropical northeast Pacific previous estimates. higher spatial reveals details such modulation due sea ice off coast Antarctica. first publicly available
