Description
During the 1960's experimental and operational meteorological satellites carrying thermistor bolometer sensors were in orbit during about 60 months. Our paper presents a synopsis of results from these measurements.

Description
Bulk models of the planetary boundary layer (PBL) conventionally rely on diagnostic forms of the turbulence kinetic energy (TKE) equation to determine the entrainment rate. During episodes of rapid deepening or shallowing, the local time rate of change of the vertically integrated TKE becomes significant compared to the difference between gross production and dissipation. A method is presented to determine the entrainment rate in a bulk PBL model...

Description
A one-layer bulk boundary layer model is developed following earlier work by Randall and Moeng. The model predicts the mixed layer values of the potential temperature, mixing ratio, and u- and v-momentum. The model also predicts the depth of the boundary layer and the vertically integrated turbulence kinetic energy (TKE).

Description
For several days at the end of January and the beginning of February 1972, the components of short-wave radiation were measured over a snowfield in a valley of the Rocky Mountains at a height of 2700 m above sea level.
