Disclaimer

We urge users of any scientific data to carefully interpret the data, including the data presented in the figures and tables on this website, so that one does not draw erroneous conclusions.  The overall uncertainty associated with the data is a combination of uncertainties associated with the instrument and those introduced during the creation of the data product, which is a multi-step and sometimes imperfect process that may lead to inaccurate data for some areas (e.g., Duncan et al., 2014). In addition, for many places in the world, there are few, if any, independent observations with which to evaluate the satellite data.

Data discovery, visualization, and analysis resources for the end-user.
