Data for manuscript:"Atmospheric and cryospheric observations at the high-altitude Zarafshon River Basin and the hydrographic party glacier (GGP), Tajikistan"

These data are atmospheric and cryospheric observations made at the GGP glacier in Tajikistan between 2018 and 2025. The data consists of autumn expedition observations (2018, 2019, 2021, 2023, 2024 and 2025), as well as continuous meteorological observations at the site. Observations include - Glacier surface area and evolution with in situ, UAV-based and remote sensing observations - Meteorological measurements - Glacier snow and - ice properties including impurities - Atmospheric aerosol observations The observations tell about the state of the GGP glacier, its evolution and environmental drivers of that evolution. The data are organized in thematic .zip- folders: Atmospheric aerosol measurements.zip particle concentration particle size distribution_PM (particulate matter mass distribution) BC (black carbon mass concentration) UAV_aerial_photography.zip UAV_DSM (digital surface model) UAV_mosaic (orthomosaic overlay) Weather.zip weather (weather station data) Terminus coordinates.zip GGP Terminus coordinates in situ GGP Terminus coordinates 3rd party (1973 expedition + satellite imagery) Snow impurities.zip snow impurities, pit profiles snow impurities, surface samples Ablation stakes.zip Ablation stakes (coordinates and height) Surface reflectance.zip surface reflectance In addition, links to external data repository (lake.fmi.fi) is provided for: Trail camera photos Individual tiles + photos for UAV_DSM and UAV_mosaic UAV- 3D imaging project data for propietary Pix4D- program
