NEW PATCH AVAILABLE -- V1.0i (Precipitation, etc)

Digital Atmosphere Workstation Patch V1.0i is now available at:
http://www.weathergraphics.com/download.htm
Changes from V1.0h to V1.0i (6/15/04)
* PRECIPITATION. Precipitation from observations now fully supported. Instead of being carried in one variable, variables are now provided for the full range of precipitation times (1, 2, 3, 6, 9, 12, 15, 18, and 24 hr) so they can be plotted and analyzed independently. Contour codes now added for these (PC01, PC02, PC03, PC06, etc) and a new precipitation menu has been added (reflected in digatmos.mnu). A trace of precip is always treated as 0.1 mm (the difference is like splitting hairs anyway). The internal unit of measure for precipitation in Digital Atmosphere is tens of mm, and -9 means zero precipitation while -9999 means missing precipitation. Note that there are some difficulties due to poor coding standards: for example in METAR there is no way to differentiate between a station that observed zero precipitation and one that does not even encode precipitation, so in METAR it is always assumed zero precipitation was observed if no precipitation group was carried. This could affect the contours, but I have no idea about what else to do. SYNOP should behave appropriately since the iR group says explicitly whether precip is not observed or is simply zero.
* MM TO INCHES CONVERSION function MMIN is provided and is used in the new precipitation menu (which uses English measures by default, though the original data is stored internally in tens of millimeters).
* QUALITY CONTROL PANEL has been changed to allow the new precipitation variables to be viewed and modified.
* CONTOUR LABELS now allow decimal fractions, depending on the contour interval that is set. This allows labels like 0.05, 0.10, 0.15 (inches), etc.
* ANALYSIS MENU does not produce extra 'blank' selections anymore when dead carriage returns are entered in the digatmos.mnu file.
* CONTAINS THE TWO MISSING SKEW-T FILES (skewblnk.bmp and skewblnk.cfg) that were accidentally omitted from Tuesday's v1.0h build.
