Marine Barometer im Vergleich zu Tide Pro Nutzung und Statistiken

Marine Barometer is a barometer sensor interface that is uniquely designed to meet the needs of mariners who rely on accurate atmospheric pressure for weather routing and the evaluation of weather maps. Pressure readings can be manually saved permanently along with the latitude, longitude, and time of the reading. If a sensor offset has been applied, that value is also stored with each recorded pressure. These recorded pressures can then at the navigator's convenience be transferred to the vessel's printed logbook. The GPS sensor is accessed for latitude and longitude only. The elevation of the sensor (your iOS device that includes a barometer) above sea level must be entered manually. Elevation values from the GPS are not accurate enough for the intended application. A sliding average of the pressure displayed over the past 14 seconds can be engaged to account for the change in sensor height in the presence of waves and swells at sea so that an accurate sea level pressure can be obtained. The concept of sea level pressure is explained along with how it is determined from the sensor reading. Instructions are provided on how to check the calibration of the sensor, and a sensor offset can be applied as needed. Links to sources of accurate sea level pressure are included. Sources of accurate elevation are included for use on land. The standard units for marine applications are millibars (mb) or hectoPascals (hPa). The main pressure display can also be set to inches of mercury, millimeters of mercury, or kiloPascals. However, because the primary reference pressures that would be used to check the sensor calibration are in mb, the sensor calibration must be set using millibar units. Reference links are provided for learning more about the tactical use of pressure for weather forecasting and weather map evaluation. Discounts are offered for barometer related reference books.

Tide Pro

Tide Pro developed by www.9oc.net and published in September 2020. If you are into fishing, beach combing, surfing, sailing, or wild fishing, this app will provide you high-precision forecast of ocean weather. Providing global tides,waves,currents,sea temperature, salinity ,wind and surface temperature field of water less than 10-km grid precision for fishing ,travel and leisure, fishing and aquaculture. Main benefits: 1.Astronomical tide¤ts forceast:upgrading algorithm of tide model in December 2021,grid precision significantly improved compared to the previous model.Support offline access to the real-time tide and moon phase of favorite sites. 2.6-Day storm surge forceast:Storm surge is the rise in seawater level caused solely by a storm.Storm surge is the abnormal rise in seawater level during a storm, measured as the height of the water above the normal predicted astronomical tide. This model output is NOT total water level guidance, Total tide resulting from the combination of storm surge and the astronomical tide. Actual water levels can be significantly higher than forecast due to waves, steric effect and other components not presently included in This model. 3.Merged Ocean-Currents approach a practical velocity at sea surface. The total current is obtained from the simple addition of contributions from the oceanic general circulation,waves (e.g. Stokes drift) and tides(the exchange between the coast and the open sea). Support access to the speed and direction of Merged Ocean-Currents, the speed and direction of oceanic general circulation,sea surface height and sea surface temperature. 4.Ocean wave forceast: support access to wave height, wave cycle, wave direction and 3 categories of wave data. 5.Ocean currents forceast: support access to current speed, direction, temperature, salinity data of both superficial current and 50 varied depths currents. 6.Ocean bio-chemistry forceast: support access to 10 marine bio-chemistry values including chlorophyll, phytoplankton, PH value, primary gross product of plants, etc. 7.Seabed elevation: support access to data of seabed elevation. Grid precision is less than 0.5-km. 8.Weather(Field water temperature/soil temperature):support access to water temperature and soil temperature of 4 different depths. Please be kindly notified:We cannot guarantee the accuracy of numerical forecasts, and Only supplies the reference.
