The Stratospheric aerosol layer is a key component of the climate system with global implications on surface temperature and the hydrological cycle. Being highly variable, regular observations are needed to understand its different sources.
The Balloon Network for stratospheric aerosol Observations (BalNeO)aims to provide key in situ measurements of stratospheric aerosols.
BalNeo brings together research laboratories from USA, Brazil, France and India to profile aerosol properties from the ground to the stratosphere. BalNeO is the heritage of a decade of balloon deployments [2014-2025] across the world
funded by the Upper Atmospheric Composition Observation program at NASA Langley.
Data from several campaigns including, the Balloon measurement campaign of the ATAL (BATAL),
the Brazil Volcano project (BraVo), Rapid Balloon Experiments for Sudden Aerosol Injection in the Stratosphere (REAS), the Kelud-Ash project (Klash)
and Volcano rapid response campaign after the 2018 Kilauea eruption (VolKilau) are archived here.
