Automatic weather stations (AWS) play a prominent role in making meteorological measurements in remote areas. These measurements can feed into climate models; providing better projections for rainfall, temperature and more. This peculiarly perched piece of equipment is just such a weather station: Out in the Swiss Alps, this AWS is making measurements of temperature, precipitation, wind speed, rel ...[Read More]
