ESA launches EarthCARE satellite to study the impact of clouds on #ClimateChange

The #EarthCARE satellite - a collaboration between #ESA and Japanese space agency #JAXA - will study how the formation of #clouds and the density of #aerosols in the #atmosphere impact the Earth's temperature.

Wondering about putting some sort of geospatial meetup on the #emfcamp schedule - just a time to meet in the lounge/bar and geek-out about geo. What do you think @Emily_S @ultrazool @Laura (I think I got the right Laura!) and anyone else geo I know going?

How Accurate Are Existing Land Cover Maps For Agriculture In Sub-Saharan Africa? [metrics]

Map showing the number of maps that predict cropland in each 10 m/pixel location. Panel A shows the maps in the context of the African continent while Panel B gives larger views of the maps (countries not to scale). Blue and red indicate regions of high or unanimous agreement between maps for the crop and non-crop classes, respectively. Yellow indicates regions of high disagreement between maps.

Skin Walker Ranch mystery.

Yeah, right.

Same principle governs side-scan sonar & aerial photography. Whether sonar or sunlight, we can tell something is on the surface or in the air/water column by its shadow. A low angle light source with the shadow connected to the object means the object is on the surface. #science #RemoteSensing
