STPSat-1 (IMAGE) Naval Research Laboratory Caption This is a comparison of NOGAPS synoptic weather fields for 82 km for 18 UT (Universal Time) on June 13, 2007. Shown are maps of (a) temperature, (b) abundance of water vapor (parts per million by volume) and (c) resultant saturation (proportional to relative humidity). Values greater than 1 represent super saturated air. The three red dots are locations of ice clouds observed by SHIMMER near this time. No clouds were seen in the sub-saturated air.
