Help Document Index

This is file is the master index of other help documents that you can request from this mail server. Previously we had all the instructions in a single message but it was becoming unwieldy for some users to download over limited connections such as SailMail. Therefore we have sliced the documentation into a number of sub-documents which you can easily request using the links below.

Note: In general you probably want to retrieve all three of the following help files

Index Filename



GRIB Files. This document describes how to automatically request binary GRIB data. NOTE: You will need a viewer program in order to do something useful with this data. Please see:


Textual weather reports. This document describes how to automatically request a variety of weather forecasts and reports that are available in text format (ie no pictures). Text format weather files will download much faster than graphical forecasts over slower internet connections


Graphical weather reports. This document describes how to automatically request a variety of weather forecasts and reports that are available in graphical format (ie they are pictures). Beware that on slower internet connections it may take several minutes to download each picture, so don't order too many at one time
