Consolidating the Two-Stream Inversion Package (JRC-TIP) to Retrieve Land Surface Parameters from Albedo Products
The objective of this paper is to present a series of improvements on the Joint Research Centre Two-stream
Inversion Package (JRC-TIP) that enhance its effectiveness to generate
reliable surface products and associated uncertainties from surface albedo values. Look-Up Tables (LUTs) are
built in the observation space from the JRC-TIP and they are used to store solutions obtained from off-line
dedicated procedures on selected sets of prior conditions. This new approach drastically limits the occurrence
of questionable solutions, revealed by outliers in the retrievals, often associated with local, instead of
global minima, and ensures that the retrieved values are insensitive to small variations in the input albedo
values. This TIP table based approach also reduces considerably the computing time requirement, a definite
asset in the systematic application of the TIP against large data sets of surface albedo products.
