Hi - This seems strange. I've been running through the entire VIIRS mission doing match-ups with in situ observations collected in the Great Lakes. My match-up routine is coded in IDL. The code happily chunks through the data from 2012-2016 but then stops with an error ("H5A_READ: unable to read attribute: Object ID:....") when it gets to 2017. The attribute I am trying to read when the error occurs is "day_night_flag." None of the other attributes (e.g. "easternmost_longitude") I'm reading in the code has a problem. When I bypass checking the day_night_flag, the code runs through all the data without error. Here are example code snippets (using a 2016 file and a 2018 file as examples). I have checked the header dumps and don't see any differences. Any idea what is going on? Thanks, Barry
