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
Polar Environment Atmospheric Laboratory (PEARL)
Project Lead: Dalhousie University
Location: Eureka, Nunavut
* [up to $1,793,678]
The Polar Environment Atmospheric Research Laboratory (PEARL) in Eureka, Nunavut is the most northerly university-led atmospheric research facility in Canada. PEARL is one of the very few atmospheric observatories in the High Arctic and the only one in the Canadian sector. The ridge laboratory was constructed in 1992. The laboratory has been operating in its present form since 2005. Funding will allow the facility to upgrade its telecommunications capability to transfer scientific data and communications to and from this remote location. Funds will also be used to renovate the facility’s infrastructure to allow for increased science capacity. These upgrades and renovations will also improve
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) ...
