Description: (1) The compressed archive 'L1B2 Soft Win.zip' includes the self-contained, executable IDL Virtual Machine software package that allows processing MISR L1B2 data without requiring an IDL license. Users who do have access to an IDL license are encouraged to obtain the necessary source codes from the GitHub web site https://github.com/mmverstraete (Verstraete et al., 2019, https://doi.org/10.5281/zenodo.3519989) and to incorporate those functions in their own custom programs.(2) The document 'L1B2_Soft_Win.pdf' provides the User Manual to install and use the software package 'L1B2_Soft_Win.zip' on a PC running under the MS Windows operating system.In addition, the authors provide the test input data archive 'L1B2_input_68050.zip', available from Verstraete et al., 2020, http://doi.org/10.5880/fidgeo.2020.012, to allow users to explore for themselves the various steps of this missing data replacement process in actual MISR L1B2 files.Background information:The Multi-angle Imaging SpectroRadiometer (MISR) is one of the five instruments hosted on- board the NASA Terra platform, launched on 18 December 1999. It features 9 cameras pointing at various angles along the track of the platform, each measuring the amount of solar radiation reflected by the Earth in 4 spectral bands. MISR started acquiring observations on 24 February 2000, and is still operating as of this writing, therefore providing 20 years of continuous global observations.One of the most basic data products generated by NASA after the initial pre-processing of MISR raw data is the Level 1B2 Georectified Radiance Product (GRP). This data product intermittently contains missing data that are often due to a temporary overload of the on- board computer. This process, which results in the dropping of lines of measurements while the computer resets itself, tends to occur especially when the MISR instrument is switched from the default Global Mode (GM) to the occasional Local Mode (LM) of operation, and conversely. As a result, those missing lines are unevenly distributed and tend to cluster around particular sites and dates.
