Air-quality forecasting for the Pacific Northwest



The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite was launched by NASA on April 28, 2006. The CALIPSO images below were derived from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument, which probes the vertical structure and properties of thin clouds and aerosols over the globe. For more information about CALIPSO please see:

Expedited CALIPSO browse images have a processing latency of about 12 hours. These products use degraded attitude information, a simple calibration scheme based on climatology and are made available to support operational forecasting activities. For the standard product images and data for dates prior to 2011 please visit the CALIPSO site.
