Abstract: Until recently, investigations of the temperature structure of the planetary boundary layer have been confined to the use of balloon soundings (tethered balloon sondes, rawinsondes), disposable drop-sondes, or high performance ...

Abstract: Particulate lead, aluminum, sodium, vanadium, manganese and iodine, vapor phase iodine and ice nuclei were measured simultaneously in Providence, Rhode Island, over a period of one year. Interrelationships found were ...

Abstract: The Storm Peak Laboratory (SPL), operated by the Atmospheric Sciences Center of the Desert Research Institute, is now located in a newly constructed permanent building at elevation 3210 m (10?530 ft) above mean sea level ...

Abstract: Cloud-droplet spectra and coincident cloud water pH measurements have been made for a portion of ten consecutive winters (1983/84?1992/93) from clouds that enveloped Storm Peak Laboratory in northwestern Colorado; cloud ...

Abstract: A persistent cold-air pool in the Yampa Valley of northwestern Colorado was simulated with the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5). The observed ...

Abstract: Digital data from the National Oceanic and Atmospheric Administration Advanced very High Resolution Radiometer (AVHRR) satellite instrument provides multispectral images in visible near-infrared and thermal infrared wave ...

Abstract: Pollution aerosols acting as cloud condensation nuclei (CCN) have the potential to alter warm rain clouds via the aerosol first and second indirect effects in which they modify the cloud droplet population, cloud lifetime ...

Abstract: Supercooled cloud droplets were inertially impacted onto ?cloud-sieves? at a mountaintop location. The large cross-sectional areas of the sieve meshes permitted grams of cloud water to be passively collected in minutes. ...
