Is zone a postal zip or what? They are a "weather zone". Forecasts are made on larger zones that usually cover several reporting stations. That's what the zones are for. The 'radar' value is an even larger area (especially near the Arctic and Antarctic due to the location of the satellites at the equator. The available North American radar areas are "East CONUS, West CONUS, Puerto Rico, Alaska, and Hawaii. Related zones are available for hurricane areas. I will admit that I have no idea about gathering information for areas outside of the US. I suspect you will need to try tracking down sources of satellite and forecast data for Poland, if any, from some European weather agency. > I wanted to update info on Polish cities.

The top of te file contains the list of regions: NA EU AF OZ ME AS M_ AT for N. America, Europe, Africa, Australia/New Zealand, Middle East, Asia, Central and South America, and Atlantic. Each of those regions has a list of more local regions, usually countries or, for larger countries, states. While weather has been a hobby of mine for many years and I have set up the initial weather web page for Lawrence Livermore National Lab many years ago when I worked there (http://www.llnl.gov/llnl-bin/weather), I am a long way from being a meteorologist. I am uncertain how many of the NOAA designators have any international parallels. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
