The HPWREN camera archive contains millions of images that, when formed into time-lapse movies, can be used to illustrate subtle changes over long periods of time. Many examples of this have been created with a focus on the Earth, for example a La Cima time lapse video of the vegetation regrowth over many years after the Cedar Fire in 2003, but the images also capture some of the sky above

The HPWREN cameras have been recording images minute after minute for the past several years, and this cache of data may be useful for demonstrating basic concepts in astronomy such as the seasonal changes in available sunlight. Time-lapse videos created from these images may help students in introductory astronomy classes better understand the Earth's tilt as it orbits the Sun and the effect this has on our lives.

Using HPWREN camera images for fire ignition detection

HPWREN staff have been discussing fire plume detection via its camera infrastructure with various projects for a number of years. Over the last few years technologies in the areas of Deep Learning and Edge Computing have matured to a point where real-time image analysis at the origin location of the images is becoming feasible.
