I'm looking for a postdoctoral researcher to join my group at Carnegie Science, now based at Caltech in Pasadena. If you're interested in land-atmosphere interactions and how they're influenced on small scales by microclimates, please take a look at the ad! apply.interfolio.com/190703
Jeff Dukes, on his hands and knees under a thick canopy of chamise chaparral at Jasper Ridge Biological Preserve, smiles down at a camera on the ground below him after installing a microclimate sensor.

A data center drained 30M gallons of water unnoticed — until residents complained about low water pressure
Residents in Fayetteville, Georgia, noticed low water pressure last year. The utility discovered two unaccounted-for water connections at one of the nation’s largest data center campuses.
