The solar irradiance reflected up to a spacecraft from the surface of the Earth can be used to calculate reflectivity. Reflectivity calculated for specific bandwidths is needed for the calculation of total column ozone from the TOMS and OMI instruments. Reflected radiation can come from two surfaces, the ground, and the tops of clouds. Reflectivity is determined from the measurements at 380 nm, or 360 nm in the case of Earth Probe. Clouds are clearly defined and recognizable in images produced using TOMS and OMI reflectivity data.

We organize our data and image products by the dates a specific spacecraft returned data. Select from the buttons below to get images and data for the dates of interest.
