STEREOCAM consists of three pairs of stereo camera setups that aim to provide synchronized and stereo calibrated time series of images that can be used for 3D cloud mask reconstruction. Each camera pair is positioned at approximately 120 degrees from the other pair, with a 17°-19° pitch angle from the ground, and at 5-6 km distance from the ARM Southern Great Plains observatory to cover the region from northeast, northwest, and southern views. Images from both cameras of the same stereo setup can be paired together to obtain 3D reconstruction by triangulation. 3D reconstructions from the ring of three stereo pairs can be combined together to generate a 3D mask from surrounding views.
Diagnostic Plots
Movie
Watch the movies to ensure the images are free of problems (e.g. dirt accumulation) and the scene is changing.
The STEREOCAM is located at E43, E44, and E45. All locations operate similarly.
There are currently no known odd behaviors for this instrument. Document some here.
Past problems that do require mention in DQAs and possibly DQPR submittal:
Dirt/Dust Accumulation
As documented in DQPR 7306, enough dirt accumulated that it was affecting data quality. When you notice that dirt has accumulated on the camera window, please issue a DQPR to have the STEREOCAM checked for cleanliness.
Ice Accumulation
As documented in DQPR 6883, ice accumulated on the camera window. When you notice such a period, please submit a DQPR to track it.
Fire Nearby
The image below shows an instance where a fire got particularly close to the camera. If something like this happens again in the future, please submit a DQPR to ensure that all is in order.
