Parsec vzw is a non-profit organization from Belgium which consists of several websites about Astronomy, Space, Space Weather, aurora and related subjects. Many of the programs aim to be an all-in-one navigation and planning package and include tools for managing GRIB files, weather routing and real-time monitoring of the boat’s instruments. Meteorologists use IR images to forecast/view: Water vapor is detected for its energy emitted in the infrared to terahertz range of the spectrum. Two fronts approach the area leading to more clouds and another blast of winter-like temperatures for next week. Both are collectively known as TIROS-N. TIROS 1, the first weather satellite in existence, was polar-orbiting, meaning it passed over the North and South Poles each time it revolved around the Earth. For coastal areas worldwide the company also combines local observations to provide high-resolution GRIB files at 8km and 1km resolution. SailDocs is very easy to use and is well suited for limited bandwidth connections. This extended view also helps meteorologists spot weather systems and patterns hours to days before being detected by surface observing instruments, like weather radar. There are many other programs available to download GRIB files, though these are the most popular.

Additional information. The snowstorm is heavy and lasts a long time. Several programs read a TWA\TWS CSV format. In the coming days, the conditions over most parts of the Mekong sub-region are expected to remain generally dry, with the exception of the eastern and southern coastal regions, where isolated showers are forecast. You need to understand the weather forecast models, the boat’s performance data, and the isochrone routing model. Global Marine Networks or GMN (globalmarinenet.com) also offers seven-day wind forecasts, available for download or via email, optimized for low-bandwidth connections. These models are designed to calculate what the atmosphere will do at certain points over a large area, from the Earth's surface to the top of the atmosphere. Once you have the optimized route, it is helpful to load the route into a chartplotter or a computer with a navigation program to track your progress. Proper routing can save hours, if not days, on long-distance passages and—more importantly—adds to the safety or comfort of the trip. And at this increased distance, both image detail and views of the poles (due to Earth’s curvature) are lost. The intensity of radiation emitted in all three of these bands, or "channels," is measured simultaneously, then stored. (i) The weather symbol in each sector indicates the weather conditions affecting or forecast to affect that sector over the next 2 hours. In order for geostationary satellites to keep pace with Earth, they must orbit at a greater distance from it (an altitude of 22,236 miles (35,786 km) to be exact). The United States currently operates two geostationary satellites. In planning for the upcoming 2016 Pacific Cup—a race that takes sailors from San Francisco to Oahu, Hawaii—I was interested in tools for predicting the optimal route.

Climate Forecasts - These forecasts show predicted trends for areas experiencing drought depicted in the U.S. Drought Monitor, as well as indicating areas where new droughts may develop. The WS-8482-X3 package includes three wireless thermo-hygrometers and the display console also measures temperature and humidity, for a total of four monitoring locations. All of the programs export the route to a GPX or KML file. A comprehensive propagation resource compiled by Tomas Hood, editor of the propagation columns of CQ, CQ VHF, Popular Communications, and Monitoring Times magazines. Called POES (short for Polar Operating Environmental Satellite), one operates during the morning and one during the evening. This website relays data and imagery from the following sources. Except instead of transmitting data back to Earth that powers your television, XM radio, or GPS navigation system on the ground, they transmit weather and climate data that they "see" back to us in pictures. Sold Out 308-1417BLV2 Weather Station with Forecast and Atomic Time. Water vapor images are sometimes color-enhanced for better viewing. WindAlert LIVE WIND gives you an insanely addicting view of the wind! The key component of weather routing is the forecast data, which is available from several sources, including the National Weather Service (NWS), NOAA’s Global Forecast System (GFS) and the Canadian Meteorological Centre (CMC).
