Chapter 3, Overview of Aviation Weather Information 3-35 3.4.2.22 Products with Temperature Information Table 3-25. Weather Element: Temperature Type: text (T), graphic (G), image (I), voice (V) Temperature Aloft Information Contained In: Type Summary Note: Temperatures are in degrees Celsius (°C) Observations METAR, SPECI (ASOS, AWOS, ATIS) T, G, V Surface temperature is included. PIREP/AIREP T, G, V Temperature aloft is included if reported. Analysis Upper Air Analysis T, G At select pressure levels, the wind direction and speed are displayed in tens of degrees and wind speed is in knots. Freezing Level Analysis G Temperatures aloft can be indicated with limitations. Depicts the freezing level at the lowest altitude in the atmosphere over a given location at which the air temperature reaches 0 °C. RTMA T Surface temperature is included. Advisories Forecasts Winds and Temperature Aloft T, G The text format provides the temperature aloft in a coded format for select height levels and locations. Graphical format provides contours of temperatures aloft. Low-Level SIGWX G Temperatures aloft can be indicated with limitations. Multiple freezing levels can be forecast when temperatures are 0 °C at more than one altitude aloft. WAFS G Global forecasts include temperatures aloft, at selected height levels, from model data in a grid point format. Upper Air Forecasts G Computer model outputs for temperatures aloft at select height levels (available levels vary depending on the model). Depicted using contours (isotherms).
