<html><head></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Dear All,<div>Brian and I are pleased to announce a new release of GrADS, version 2.0.2. Support has been added for new GRIB2 products: probability forecasts and aerosol products (product definition templates 5, 9, and 48.) This release also has a set of new functions for getting and locating the min and max values over an area: amin, amax, aminlocx, aminlocy, amaxlocx, and amaxlocy. These are more efficient than using nested min() or max() commands, similar to the use of aave() compared to ave(). There is another new function atot() which is like asum() but weights each grid box by its area. The lterp() function has been beefed up with options that exist in the old regrid UDF and its modern counterpart, re(). Now you can interpolate between grids using an area average as well as bilinear interpolation; a bessel interpolation may also be used to improve bilinear interpolation in areas of sharp gradients. Another new feature is the addition of a third argument when drawing scatter plots for colorization of the marks. This release also has important bug fixes for the reading of 2-byte data, the drawing of streamlines, and the handling of ensemble data with xdfopen. The full text from the ChangeLog is below, please read it carefully, and please look at the new and updated documentation pages. </div><div><br></div><div><div>The GrADS downloads web page (<a href="http://iges.org/grads/downloads.html"><font color="#001fdf" style="color: rgb(0, 31, 223); "><u>http://iges.org/grads/downloads.html</u></font></a>) has been updated with links to the source code and pre-compiled binaries for 64-bit linux and Mac OS X. Binaries for additional operating systems will be posted as they become available.
