    I have LandSat 8 that I downloaded from USGS Glovis and most of them I have no clouds. There are a few of them are at under 10 percent cloud cover. There are some of the Landsat I have some smoke or haze. Is it possblie for me to remove them in ENVI 5.0 ? My thoughts is that there is no way to do that and maybe wait and find a different date or month ? I am new to ENVI 5.0 and how do I do if there is a possible to do that ? Thanks.

    Removing clouds is not something easy to complete. Indeed when a cloud is present on an image it prevents the radiation to be transmitted. You could eventually mask them using the Masking tool in ENVI and process only area without clouds. Note also that you can find different approach in the literature to try to remove them: Regarding atmospheric effects: there is an additional module to ENVI called ACM for Atmospheric Correction Module that allows to correct the effect of the atmosphere on the satellite images. If you are interesting in such tool feel free to contact your Sales representative for ENVI product family. You can find more information about this module at the following page: http://www.exelisvis.com/docs/AboutAt...
