MESSIR-AERO & the Gridded Forecasts COROBOR designs software for Aviation & Meteorology for 16 years. 480 MESSIR-AERO Workstations for Pilot Met Briefing are currently operational around the world. This presentation will show some MESSIR-AERO outputs for: Ø Global Gridded Elements (wind direction, temperature. . . ). Ø The New Gridded Elements.

MESSIR-AERO & the Gridded Forecasts A SIGWX chart is based on information extracted from thinned GRIB information and data from WAFC regarding max wind speed, tropopause and geopotential.

MESSIR-AERO & the Gridded Forecasts Jet stream core position and height are extracted from WAFC GRIB data. The same data source is used for tropopause level. The software determines jet core position, altitude and speed based on the max wind speed and associated heights.

MESSIR-AERO & the Gridded Forecasts The necessary information for users is available on single layer or multiple layers. In order to have a complete image, a multi-layer display is extremely suggestive and can be used at a glance. Maximum CAT potential

MESSIR-AERO & the Gridded Forecasts RGB overlaying is extremely easy to interpret and, based on users’ suggestions, some of the layers can be compacted in display in order to have a broad image.

MESSIR-AERO & the Gridded Forecasts In the example below, the five levels of icing potential are displayed in three colors: blue for 700 h. Pa, green for cumulative 600 / 500 h. Pa and red for 400/300 h. Pa.

MESSIR-AERO & the Gridded Forecasts The final image is very easy to analyze, taking into account the combinations of colors and intensities. As examples, bright white involves a high risk of icing at all levels and light yellow is showing icing at medium and high levels i. e. between 600 and 300 h. Pa.

MESSIR-AERO & the Gridded Forecasts Areas of significant weather and CB clouds are delimitated using five different thinned GRIB data types: CB tops / base, EMBD CB tops / base and CB extension. One of the alternative display modes regarding CB is similar to a satellite visible imagery.

MESSIR-AERO & the Gridded Forecasts Color intensity is directly correlated with the risk of icing or turbulence In case of icing: at 400 and 300 h. Pa Cumulated icing risk between 700 and 400 h. Pa Cumulated icing atlevels 400 and 300 h. Pa Icing Cumulated risk only icing atrisk 700 h. Pa riskonly between at 700, all 600 and 500 h. Pa 300 h. Pa

MESSIR-AERO & the Gridded Forecasts Icing at all levels Cumulated icing risk at 700, 400 and 300 h. Pa Icing risk only at 600 andrisk 500 h. Pa Icing risk only 700 h. Pa Icing risk between 600 andat 300 h. Pa
