Book Description
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).

Book Description
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 Description
Snow characterization measurements acquired during SNOW-TWO/Smoke Week VI are presented. A summary of data for 8 days in January 1984 is given. 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.
