We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

| MISR Aerosol Climatology Product Quality Statement | Here is a description of the document: This document is a Quality Statement for the MISR Aerosol Climatology Product (ACP), dated December 1, 2007, authored by Ralph Kahn and Michael Bull. It describes the ACP, which is a key input to the MISR (Multi-angle Imaging SpectroRadiometer) aerosol retrieval algorithm. The ACP defines mixtures of up to three component aerosol types—characterized by particle size (small, medium, large), single-scattering albedo (dirty, clean), and shape (spherical, nonspherical)—that are compared against observed radiances to retrieve aerosol optical depth. The product consists of three parts: the Aerosol Physical and Optical Properties (APOP) file describing individual aerosol components, the Aerosol Mixture file specifying component mixtures, and the Aerosol Clim-Likely file providing a global monthly climatology of aerosol amount and type. The statement highlights major changes, known problems, and limitations in the product version, including updates to dust models, revised particle size thresholds, and the removal of fields related to particle hydration state. |

| MISR ARCTAS Images | This document is a daily image catalog for the MISR (Multi-angle Imaging SpectroRadiometer) instrument in support of the ARCTAS (Arctic Research of the Composition of the Troposphere from Aircraft and Satellites) campaign during 2008. It is organized as a tabular index of MISR observations over several Arctic and sub-Arctic sites—including Cold Lake, Great Slave Lake, Fairbanks, and NSA Barrow—spanning from April through July 2008. For each observation date, the document lists the orbit number, orbital path, and target site, along with links to downloadable imagery in JPEG and TIFF formats across multiple data products: standard-resolution nadir and 70° aft camera images, local-mode full-resolution nadir and aft camera images, aerosol optical depth maps at 17.6 km resolution, stereo height retrievals at 1.1 km resolution, and composite images. The catalog also notes where data were unavailable or where no local mode acquisitions occurred for a given overpass. | PDF (923.47 kb) | Aug. 20, 2024 |
