A McIDAS program has been written to filter bad pixels (shot noise) and bad scan lines out of GOES images.  This program works on 2-byte GOES data, unlike the program provided with McIDAS which works on 1-byte data only.  The filtering program was needed to eliminate values that caused the generation of bad image products when these pixels and lines are not eliminated.  This program can also be used to eliminate bad pixels that affect statistics or composites/climatologies generated from 2-byte GOES imagery.

A GOES longwave infrared difference product (channel-4 minus channel-5 difference) has been added to RAMSDIS Online Experimental (ROLEX).    This product was requested for comparison to the equivalent channel difference product available on AWIPS.

An explanation of the channel-4 minus channel-5 product and what it shows is available on ROLEX.  ROLEX can be found on the RAMSDIS Online homepage found at: http://www.cira.colostate.edu/ramm/rmsdsol/main.html

A paper entitled "GOES Derived Product Imagery: Statistical comparison to radiosonde observations and use in forecasting severe convection along a dryline" has been written and is currently undergoing internal review.  It will then be sent to Weather and Forecasting.

The GOES Autoestimator rainfall estimation product was added.  This product was added in preparation for upcoming GOES Assessment Activities.
