The HM-1 HAZMAT weather station is designed for first responders to hazardous material incidents. The weather station provides important real-time information for monitoring and responding to incidents. The station works in conjunction with CAMEO/ALOHA software that enables responders to monitor plume dispersion. CAMEO was developed by Chemical Emergency Preparedness and Prevention Office (CEPPO) and the National Oceanic and Atmospheric Administration Office of Response and Restoration (NOAA). The software was developed for front-line chemical emergency planners and responders. CAMEO helps in evaluating and predicting dispersion patterns. The portable nature of the HM-1 and its long range radio allows responders to monitor the situation in real-time and from a safe distance. The HM-1 includes a radiation detector to give first responders an early warning to the presence of radiation. A robust, high strength Windsonic sensor is available for upgrade.
