Holographic Detector for Clouds (HOLODEC-II) IOP2

Project:

ACE-ENA

Summary

This dataset contains measurements of cloud particle size distributions collected during the ACE-ENA project (IOP2) using an airborne holographic instrument mounted on the DOE G1. The HOLODEC-II is a second-generation version of a holographic detecter designed to determine the size, two-dimensional shape, and three-dimensional position of hydrometeors via digital in-line holography. Advantages vs other hydrometeor detectors are that the sample volume is not size dependent, relative positions of hydrometeors in the sample volume can be determined in three dimensions, and effects produced by shattering from the aperture edges can be identified and eliminated. Automated analysis programs have been developed to process the holograms collected and produce size distributions. HOLODEC-II has sufficient resolution to determine the sizes and locations of cloud droplets as well as ice crystals.

A separate dataset (562.002) has been created for IOP1. Please see the link below to access the ACE-ENA IOP1 dataset page.
