DOPS
Dual Optical Pulse Sensor

The Dual Optical Pulse Sensor (DOPS) is an airborne optical sensor used to study lightning in the atmosphere. It is an updated version of the Optical Pulse Sensor (OPS). DOPS collects measurements of lightning's duration, intensity, and waveform characteristics. It operates across two channels centered at 500 and 777.4 nm and has a sample duration of 0.328 seconds. It has a wide field of view (60 degrees) and can detect lightning during daytime conditions.
