The OMI surface LER database contains the Lambertian-equivalent reflectivity (LER) of the Earth's surface at 23 one-nm wide wavelength bins between 328 and 499 nm. The LER albedo values were derived from OMI data using the Doubling-Adding KNMI (DAK) polarised radiative transfer code. The model consists of an atmosphere for which Rayleigh scattering and ozone absorption are taken into account, and which is bounded below by a Lambertian surface. The surface LER is available for each month of the year and for the following wavelengths: 328, 335, 342, 345, 354, 367, 372, 376, 380, 388, 406, 416, 418, 425, 440, 442, 452, 463, 471, 477, 488, 494, and 499 nm.

Previous versions of the databases can be downloaded here.

The spatial resolution of the database grid is 0.5°×0.5°. The format and the contents of the database file are both explained here.
