Abstract

Methods, systems, and computer program products for cloud coverage estimation by dynamic scheduling of a distributed set of cameras are provided herein. A computer-implemented method includes transmitting one or more instructions to each of multiple spatially-distributed cameras in a pre-determined geographic area, wherein the one or more instructions cause each of the spatially-distributed cameras to change a context from (i) a pre-determined task to (ii) capturing one or more spatio-temporal measurements of cloud coverage; tracking the one or more spatio-temporal measurements of cloud coverage captured by the multiple spatially-distributed cameras; obtaining one or more meteorological measurements from one or more non-camera sources; and generating a cloud coverage forecast for the pre-determined geographic area based on (i) the one or more spatio-temporal measurements of cloud coverage captured by the multiple spatially-distributed cameras and (ii) the one or more meteorological measurements from the one or more non-camera sources.
