# Compressive earth observatory: An insight from AIRS/AMSU retrievals

%% Demo MATLAB file for the concept of COMPRESSIVE EARTH OBSERVATORY
% This demo file reproduces the results (i.e., Figure 4) shown in
% “Compressive Earth Observatory: An Insight from AIRS/AMSU Retrievals” by
% A.M. Ebtehaj, E. Foufoula-Georgiou, G. Lerman and R. L. Bras, _Geophys.
% Res. Lett._, Doi: 10.1002/2014GL062711.
% The results uses Compressive Sensing (CS) theory via using the $\ell_1$-norm
% regularization in the wavelet domain. The experiments are conducted on level
% II AIRS/AMSU standard rertivels of surface skin temperature (TSurfStd)[K] and near
% surface water vapor mass mixing ratio (H2OMMRSurf) [g/kg dry air] at
% resolution 0.5-degree. NOTE: the optimization algorithm, used for solving the CS problem,
% is the so-called Fast Iterative Shrinkage-Thresholding
% Algorithm (FISTA) for Linear Inverse Problems, Amir Beck and Marc
% Teboulle (2009), _SIAM J. Imaging Sci._, 2(1), 183–202,20 pp.
% Last update: A.M. Ebtehaj, 1/14/2015, Georgia Tech.

% *NOTE:* The demo is tested using MALTAB R2014b and needs the wavelet toolbox
