LiveWeather Map app analytics for December 12

-- This is an inofficial iOS App port of the Nullschool Earth Project by Cameron Beccario -- A free open weather Map to show wind, weather and oceans conditions. Height: Atmospheric pressure corresponds roughly to altitude several pressure layers are meteorologically interesting they show data assuming the earth is completely smooth note: 1 hectopascal (hPa) = 1 millibar (mb) Surface - the "Surface" layer represents conditions at ground or water level this layer follows the contours of mountains, valleys, etc. • 1000hPa ~100 m, near sea level conditions • 850hPa ~1,500 m, planetary boundary, low • 700hPa ~3,500 m, planetary boundary, high • 500hPa ~5,000 m, vorticity • 250hPa ~10,500 m, jet stream • 70hPa ~17,500 m, stratosphere • 10hPa ~26,500 m, even more stratosphere Overlay: Show another dimension of data using color some overlays are valid at a specific height while others are valid for the entire thickness of the atmosphere • Wind - wind speed at specified height • Temp - temperature at specified height • RH - relative humidity at specified height • WPD - Instantaneous Wind Power Density. Measure of power available in the wind: ½ρv3, where ρ is air density and v is wind velocity • TPW - Total Precipitable Water. Total amount of water in a column of air stretching from ground to space • TCW - Total Cloud Water. Total amount of water in clouds in a column of air from ground to space • 3HPA - 3-hour Precipitation Accumulation. Amount of precipitation over the next three hours • CAPE - Convective Available Potential Energy from Surface. Indicates the buoyancy of air, a measure of atmospheric instability and predictor of severe weather • MSLP - Mean Sea Level Pressure. Air pressure reduced to sea level • MI - Misery Index. Perceived air temperature as combination of heat index and wind chill • SST - Sea Surface Temperature. Temperature of the ocean surface • SSTA - Sea Surface Temperature Anomaly. Difference in ocean temperature from daily average during years 1981-2011 • HTSGW - Significant Wave Height. Roughly equal to mean wave height as estimated by a "trained observer" • COsc - Carbon Monoxide Surface Concentration. The fraction of carbon monoxide present in air at the earth's surface • CO2sc - Carbon Dioxide Surface Concentration. The fraction of carbon dioxide present in air at the earth's surface • SO2sm - Sulfur Dioxide Surface Mass. Amount of sulfur dioxide in the air near the earth's surface • DUex - Dust Extinction. The aerosol optical thickness (AOT) of light at 550 nm due to dust • SO4ex - Sulfate Extinction. The aerosol optical thickness (AOT) of light at 550 nm due to sulfate Projection : • Atlantis (A) • Azimuthal Equidistant (AE) • Conic Equidistant (CE) • Equirectangular (E) • Orthographic (O) • Patterson (P) • Stereographic (S) • Waterman Butterfly (WB) • Winkel Tripel (W3) Longitude : • Longitude (-360 - 360). Example: -214.68 Latitude : • Latitude (-360 - 360). Example: 14.2 Zoom : • Zoom (0-3000)
