Optimal Operation and Maximum Safety at Mexico City’s Airport
“The Doppler weather radar installed has allowed us to anticipate extreme weather events, like microbursts, guaranteeing an optimal operation of the airport’s activities and public safety.”
Engineer Daniel Aguirre Dupeyron HeadofRadarSystemsDevelopmentSENEAMMexico
Summary
In2011,NavigationServicesintheMexicanAirspace(SENEAM),theagencyresponsibleforairtrafficcontrolinallofMexico,decided to acquire a terminal Doppler weather radar(TDWR)todetectmicroburstsintherunwaysofMexicoCity’sBenitoJuárezInternationalAirport(AICM).
Thissystemenablestheconfigurationoftheairport’srunwaystobeadaptedandmadesafer,byprovidingmicroburstalertdataevery2minutesforanareaof100kmaroundthe airport. The data recorded are highly accurate andreachmaximumresolutionintherunwaysandapproachareas. All this information is received simultaneously attheairport’scontroltower,airnavigationcentreandmeteorologyservice.

“The radar was configured with the goal of optimising microburst detection and, therefore, is able to send alerts to the control tower, air navigation centre and aeronautical meteorology service every two minutes.”

Optimal Operation and Maximum Safety at Mexico City’s Airport
InordertoincreasethesafetyofAICM,SENEAMdecidedtoimplementadetectionsystemincludingaDopplerweatherradar, capable of detecting the effects of microburststhroughthemovementofwaterdrops.
MexicoCityiscoveredbytheweatherradaroftheNationalWeatherService,butthisdidnotfulfiltherequirementstobeconsideredasaterminalDopplerweatherradarandisnottrulyeffectivetodetectmicrobursts,sincethatrequiresaradarlocatedatadistanceunder12.5nauticalmilesfromtheairport,alignedwith the runwaysandperforming lowaltitudescans.
Therefore, SENEAM sought a design, installation andstart-upofaterminalDopplerweatherradar.
