; Mueller et al. 2017 ) and microwave radiometers ( Knupp 2006 ; Coleman and Knupp 2011 ) are quite useful. The AERIs measure downwelling spectral infrared radiance, from which profiles of temperature and humidity are retrieved ( Turner and Löhnert 2014 ). Similarly, thermodynamic profiles can also be retrieved from the observations made by microwave radiometers, which measure downwelling microwave radiation at multiple microwave frequencies ( Solheim et al. 1998 ). Both of these passive remote sensors

The PECAN field campaign assembled a rich array of observations from lower-tropospheric profiling systems, mobile radars and mesonets, and aircraft over the Great Plains during June–July 2015 to better understand nocturnal mesoscale convective systems and their relationship with the stable boundary layer, the low-level jet, and atmospheric bores. Large parts of the central Great Plains witness a nocturnal maximum in the frequency of thunder storms and convective precipitation in summer ( Kincer
