Thermal infrared imagery acquisition by NIROPS currently utilizes the Phoenix sensor system. Several Phoenix systems are maintained by the Forest Service at the National Interagency Incident Communications Division (NIICD) Infrared Branch. A detailed description of the technical specifications and capabilities of the Phoenix sensor is provided here. Additional airborne sensors of interest to the NIROPS program are currently being evaluated and include the Autonomous Modular Sensor (AMS) and the Wide Area Imager (WAI). The content below provides samples of Phoenix imagery for selected wildfires as well as other informational content on the NIROPS program.
