Data from occasional radiosonde campaigns and routine laboratory lamp measurements are utilized. A method has been devised to ensure stable, long-term calibration of Raman lidar measurements that are used to determine the altitude-dependent mixing ratio of water vapor in the upper tropo
Geophysical Research Letters publishes short, concise research letters that present scientific advances that are likely to have immediate influence on the research of other investigators. GRL letters can focus on a specific discipline or apply broadly to the geophysical science community.
A new Arctic stratospheric observatory (AStrO) has been established at Eureka (80 degree(s)N, 86 degree(s)W) in northern Canada. This observatory is one of the three designated components of the Arctic Primary Station of the Network for the Detection of Stratospheric Change (NDSC). Among the complement of sensors being installed at Eureka are two state-of-the-art lidar systems for monitoring stratospheric ozone and polar stratospheric clouds (PSC). The ozone Differential Absorption Lidar (DIAL) ...
