Book excerpt: This report details the design, fabrication, and operation of three new instruments that were developed at AFGL to define some of the physical characteristics of naturally falling snow. Two are devices for the measurement of fall velocity and high-resolution snow rate. The other was conceived for the documentation of the ice-crystal composition of the prevailing snow. Problems that surfaced during the first year of operation are discussed along with the plans to correct the deficiencies. Examples of the data supplied by these instruments are shown. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Measurements documenting the characteristics of naturally falling snow are being conducted to form a statistical base as input to the precipitation modeling efforts of the Cloud Physics Branch at AFGL (Air Force Geophysics Laboratory). The major part of the 1981-82 winter operations were held in conjunction with the CRREL sponsored, tri-service, SNOW-ONE-A field experiment at Camp Ethan Allen in Jericho, Vermont. This report summarizes the AFGL snow characterization measurements taken during SNOW-ONE-A. Three new instruments, designed and built to measure the fall velocities of individual snowflakes, the short-term variations in snowfall rates and to determine the crystalline structure of the prevailing snow, are described. Discussions are given on the overall operation of each instrument and examples of the resulting data are shown. Availabe results are listed in tabular form together with a preliminary data quality assessment. The initial analysis of the measurements taken during the storm of January 31, 1982 are also presented.

Book excerpt: Snow characterization measurements acquired by the snow rate meter, fall-velocity indicator and snow-structure recorder obtained during the SNOW-ONE-B field experiment are presented. Some further analyses of the SNOW-ONE-A data are also given. Correlations between snow rates, electro-optical and liquid-water-content measurements are shown with the relationships of fall velocities with these parameters are discussed. (Author).

These data consist of fall velocity, snow structure, and snowrate as recorded by Laboratory prototype equipment. A new concept of back lighting on the fall velocity indicator is discussed and data examples shown. Snowrate plots, fall velocity and crystal type information are presented for selected periods.

This book was released on 1998 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 7600 nautical miles (nm) (14,000 km) of select ice particle measurements over the United States have been compiled into a single, computerized database for use in characterizing ice crystal and snowflake (generally termed ice particle) size distributions and mass concentrations at flight altitudes. Data are from 50 research flights by six agencies in eight flight research projects using Particle Measuring Systems' one-dimensional (1-D) and two-dimensional (2-D) particle sizing probes. Primary recorded variables are average particle size distributions in the range 0.1 to 10 mm from each of 1625 microphysically uniform cloud intervals or other convenient distances in wintertime clouds, snowstorms, cirrus, and other high-altitude clouds. The findings are that, generally, the largest particles and the greatest concentrations of total ice particle mass (TIPM) are confined to altitudes below 20,000 ft (6 km). There, particles of 10 mm in maximum dimension and TIPM's up to about 3 g/m(exp 3) may be found. Above 20,000 ft, particles are smaller than 2 mm and TIPM's are less than 0.2 g/m(exp 3) in the cirrus and the upper reaches of deep winter storm clouds that are found at these levels. Exceptions are thunderstorm anvil clouds where 10 mm particles and TIPM's of at least 1 g/m(exp 3) can be found up to at least 30,000 ft (9 km). Anvil clouds and stratiform clouds associated with warm season mesoscale convective systems have provided some of the largest TIPM's, the greatest particle concentrations, and the largest particle sizes at high and mid altitudes, respectively. In contrast to supercooled cloud droplets where the largest liquid water (mass) concentrations are confined to short distances of 3 nm or less in convective clouds, the largest average TIPM's in glaciated clouds have been found in layer clouds over distances up to 30 nm.
