The performance of a balloon-borne Formvar replicator that measures continuous profiles of cloud microphysical properties is investigated. The replicator measures the small particles (<100-μm diameter) that are undetectable or poorly resolved by aircraft measurements from optical imaging probes and provides high-resolution information on ice crystal shapes.

additional samples are planned to be taken during intensive periods during the year by cascade impactors at about five of the filter sampling sites, using cascade impactors for determination of the particle size distribution of sulfur and related elements. elemental analysis is performed using proton induced x-ray emission, a highly sensitive ...

Radiosondes, ozonesondes, Cryogenic Frostpoint Hygrometers (CFH), and Compact Optical Backscatter AerosoL Detector (COBALD) backscatter sondes were launched under small weather balloons from China (Lhasa and Kunming) between 2009 and 2014 [Bian et al., 2012] to study the convective outflow of the ASM.These launches provided the first in situ measurements of aerosol in the UTLS over this region.

Areas where we can further reduce the risk of damage by wind include: Reducing the width to thickness ratio of the cable. (figure 10.4.2) By making the cable one fifth the width we reduce the wind load on the cable by a comparable amount and increase the critical wind velocity by sqrt(5) or from 32 m/s to 71 m/s (154 mph or a category 4 hurricane, table 10.4.1).

Mar 29, 2019· Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

To investigate this hypothesis, cloud and rain samples were collected simultaneously from single precipitation events, from two meteorological stations located at different altitudes: the summit of puy de Dôme Mountain (1465 m above sea level; France), embedded in clouds, using cloud impactors and high-flow-rate impingers [2], and below the ...

Two different crushing procedures are used - dry and wet crushing. Dry crushing using impactors and vibrating screens is a simpler procedure and causes less corrosion of equipment than in wet crushing; however, the process creates dust, making it difficult to maintain and keep clean. Wet crushing using screens and hydroclones is cleaner because ...
