TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 87: Test Methods for Evaluating Field Performance of Road Weather Information System (RWIS) Sensors explores field testing of environmental sensor stations (ESS) sensors in order to evaluate if a sensor is providing an accurate representation of actual conditions at the installed site. The procedures contained in this document define the equipment and describe the procedures that state, county, and city personnel can use to measure sensor parameters and evaluate sensors.
A slide presentation on the Training for Field Test Procedures for Environmental Sensor Stations program is available in PowerPoint and Adobe Acrobat formats.
