It has been very dry in the state of California for the past couple years. The lack of rain in 2013 and 2014 contributed to exceptional drought conditions in the state. Records were set over the past winter for the lowest winter snow packs recorded in a century. Rainfall produced by storms moving into California from the Pacific Ocean has recently brought some very temporary drought relief.
During the past week hurricane Odile and remnants have produced heavy rainfall that caused dangerous flooding over the Baja California peninsula and the southwestern United States. Rainfall from Odile may be welcomed in the Southwest where some areas have been experiencing extreme to exceptional drought conditions.
Images are routinely produced using TRMM Microwave Imager (TMI) data which show the global area covered by the satellite. These "Quick Look" images use Microwave brightness temperatures at 85.5 GHZ and at 37.0 GHZ combined in the red, green and blue components (guns) of the images. These false color images can be used to distinguish land from water and show the differences between land surfaces such as deserts, snow cover and sea ice. On these images areas of dry atmosphere over water appear as blue and moist atmosphere is dark blue.
