| System |   Solar with
battery storage for multi-year operation
between visits. |
||
| Location | Twenty stations covering the Greenland ice sheet | ||
| Description | Assess the daily annual and inter-annual variability
in accumulation rate, surface climatology and energy balance at
selected locations on the Greenland ice sheet. Sites are highly
sensitive to ice sheet mass balance and will be compared to climate
abnormalities predicted from modeling results. Total network of 20
autonomous weather stations located across the Greenland ice sheet each
measuring 32 parameters for hourly transmission. Each site is powered
by solar panels and power is stored in batteries. See http://www.vecopolar.com/Files/PDFs/GLAWSNetwork.pdf for map and full description. |
