This product is composed of a beta version for a product from the MODerate resolution Imaging Spectrometer (MODIS) on board the Aqua satellite. MODIS Aqua L3 occurrence frequency of low cloud types (OFLCT) is part of our global MODIS Aqua data from the 2017 MEaSUREs project, A Comprehensive Data Record of Marine Low-level and Deep Convective Cloud Systems Using an Object-Oriented Approach. This file provides the aggregated occurrence frequency of low-cloud types for the year 2007 at monthly and annual intervals. The latitude and longitude variables from MYD_L2_CB; and latitude, longitude and pred_cat from MYD_L2_MPLCT were used to calculate the occurrence frequency of six low-cloud types in 2.0° x 2.0° grids for 60°S-60°N and 180°W-180°E. The six low cloud types are Closed-cellular MCC, Clustered Cumulus, Disorganized MCC, Open-cellular MCC, Solid Stratus, and Suppressed Cumulus.
