title: RCCM.out: Samples of MISR RCCM data to explore the missing data replacement process

description: This data publication provides access to (1) an archive of maps and statistics on MISR RCCM data products updated as described in Verstraete et al. (2020, https://doi.org/10.5194/essd-2019-77), (2) a user manual describing this archive, and (3) a large archive of standard (unprocessed) MISR data files that can be used in conjunction with the IDL software repository published on GitHub and available from https://github.com/mmverstraete (Verstraete et al., 2019, https://doi.org/10.5281/zenodo.3240018). The authors also make a self-contained, stand-alone version of that processing software available to all users, using the IDL Virtual Machine technology (which does not require an IDL license) from Verstraete et al., 2020: http://doi.org/10.5880/fidgeo.2020.008. (1) The compressed archive 'RCCM_Out.zip' contains all outputs produced in the course of generating the various Figures of the manuscript Verstraete et al. (2020). Once this archive is installed and uncompressed, 8 subdirectories named Pxxx-Oyyyyyy-Bzzz are created, where xxx, yyyyyy and zzz stand for the Path, Orbit and Block numbers, respectively. At a minimum, those directories contain a 'GM/RCCM' subdirectory that includes a collection of 75 text, graphics (maps in PNG format) and binary data files relative to the intermediary, final and ancillary results generated while preparing those Figures. The 3 subdirectories for Orbit 92981, as well as the one dedicated to Orbit 78010, contain a subdirectory labeled 'GM/RCCM__[cc]-[l1]-[l2]' instead, where [cc] indicates the camera whose data have been modified to evaluate the performance of the algorithms, and [l1] and [l2] indicate the first and last line that is artificially deemed to contain missing data: those subdirectories include collections of 93 text, graphics and binary data files; they include maps of the RCCM data product before and after this artificial modification. Two of those subdirectories (for Orbits 2111 and 78171) also contain a subdirectory 'GM/L1B2', which hosts a number of text and graphics (maps in PNG format) files obtained by plotting the top of atmosphere bidirectional reflectance measured by the MISR instrument. These images can be used to verify visually the state of the cloud cover in the corresponding cameras and spectral bands. Each map is accompanied by a similarly named text file providing the legend of the corresponding map. Those subdirectories also contain log files that report on the success rate of the replacement algorithm as well as accuracy of the replacement procedure, when some data are artificially removed. (2) The document 'RCCM_Out.pdf' provides the User Manual to install and explore the compressed archive 'RCCM_Out.zip'. (3) The compressed archive 'RCCM_input_68050.zip' contains MISR L1B2 GRP and RCCM data for the full Orbit 68050, acquired on 3 October 2012. This file includes data for a wide range of locations, from Russia to north-west Iran, central and eastern Iraq, Saudi Arabia, and many more countries along the eastern coast of the African continent. It is provided to allow users to analyze actual data with the software package mentioned above, without needing to download MISR data from the NASA ASDC web site.
