Using Navimail; notes produced by David Hide, HROA.

Operation of Navimail

David Hide said, "First, download their free software (available in English or French): this is best done at home, on broadband or using a CD. This includes the MAXSEA software for decoding GRIB messages. MAXSEA is compatible with other charting programs such as Raytech. (Setting up is fairly simple, just follow the instructions.)

Secondly, create a Météo France account using electronic billing. This involves paying a minimum of €15 upfront from which charges for services are deducted. The amount on credit is then topped up from time to time. (France Telecom INMARSAT customers do not need to subscribe; the service is directly charged on their usual telecom bill)".

The system then enables automatic generation of an outgoing email requesting several types of information, which can then be sent by any standard email system, though the normal link is via Outlook Express.

Samples of services available can be seen on a Météo France Navimail page. All items are charged for, except Security bulletins and satellite images which are free of charge (except for telecommunication cost). Routine forecasts and Flash warnings messages can be ordered for a few € a month.

The GRIB service provides wind, pressure, sea state and sea temperature. The data are at 1 degree latitude/longitude intervals. Wind data can also be provided at 1/4 degree intervals, presumably from meso-scale model output. These may well only be available for 1 - 2 days ahead. However, they may give a better representation of topographic effects in such areas as the Dover Strait but not areas as small as, say Torbay or the Solent.

Queries concerning this wide ranging and useful service to Navihelp. Or see the Navimail FAQ page.
