Earth Day 2010 Open House - 2010

Grand Junction Forecast Office Open House

On April 22nd, National Weather Service (NWS) personnel in Grand Junction hosted an open house for the public. The open house coincided with Earth Day, since the NWS focuses on Earth’s atmosphere. The purpose of the open house was to show people the services provided by the NWS, how we make and disseminate our forecasts and warnings, and how people can obtain those NWS services.

A highlight of the open house was the weather balloon release at 5 PM MDT. The National Weather Service in Grand Junction sends up a GPS sonde (a small box with weather instruments) attached to the balloon at 5 AM and 5 P0M MDT each day. There are about 90 other locations in North America and nearly 900 sites worldwide where weather balloons are routinely released at the same time. The GPS sonde measures winds, temperature, relative humidity, and pressure up to an altitude of about 20 miles above sea level.
