YouCan’tSeeMosquitoesfromSpace

“I don't see mosquitoes from satellites,unfortunately, but I see the environmentwheremosquitoes are,” says Felix Kogan ofthe NOAA Satellite and Informa<on Servicein this video about his work. “Mosquitoeslikewarmandmoistenvironmentsandthisis what I see from the operaHonalsatellites.”

Seasonal paferns of temperature andprecipita<on may be altered by climatechangewhereyoulive.Changesinlanduseisalso an important factor in crea<ng newmosquitobreedingsites.

WhyCollectMosquitoData?

Globally, there is a major effort to use data fromsatellitestopredicttheonset,decline,andspreadofvector-bornediseases.Reliableground-baseddataarehelpful for the development of realis<c computermodelsbasedonsatellitedata.

Inmanypartsoftheworld,sufficient"ground-truth"dataaresimplynotavailable-soGLOBEobservaHonsare criHcally important to tracking and controllingdisease.

And- these satellites can’t disHnguish between thesites in your community-we need the “eyes in thesky”butalsothe“bootsontheground”!
