High-resolution, bias-corrected weather data for the past, present, and future

Super­charge your oper­a­tional mod­el­ing appli­ca­tions with the most accu­rate and up-to-date weath­er information 

Our mission

GloH2O lever­ages the lat­est devel­op­ments in machine learn­ing, remote sens­ing, and mod­el­ing to pro­duce the high­est qual­i­ty cli­mate and weath­er data prod­ucts. We help orga­ni­za­tions rec­og­nize, under­stand, and man­age present and future hydrom­e­te­o­ro­log­i­cal risks at any scale, from glob­al to region­al to local. Because we are com­mit­ted to serv­ing the com­mon good, we release our prod­ucts for free for non-com­mer­cial use. Please con­tact us if you would like more infor­ma­tion on any of our products.
