Radiofax and Weatherfax data can still be obtained today through the National Oceanic and Atmospheric Administration through an FTP download. Radiofax is still used to disseminate weather and climate data to shipping where the internet and phone access is limited.
Normal radio fax transmission speed is 120 lines per minute. However, 240 LPM can be achieved in monochrome or color fax.
Primary radiofax use today is primarily along coastal regions for sending weather charts and data.
In the United States, preparation usually comes from the National Weather Service of the National Oceanic and Atmospheric Administration. Information can also come from the Tropical Analysis and Forecast Branch of the Tropical Prediction Center & National Hurricane Center broadcast over US Coast Guard stations. Radiofax transmission also comes from the Ocean Prediction Center of the NWS.
In Canada, Canadian Forces Meteorology and Oceanography Center (METOC) transmits in radiofax as well as in radio-teletype.
