Jeju-2024 Cloud Probe Workshop Simulations README
The files in this folder contain synthetic Optical Array Probe (OAP) data for the Workshop on Evaluation of Cloud Probe Processing Software, in Jeju, South Korea from July 12-13, 2024.
There are three sets of files available: one for simulated round drops, one for simulated columns with a 3:1 aspect ratio, and one with a mix of irregular ice shapes. Each set of files has been simulated for four instruments:
| Probe | Pixel Resolution (μm) | Number of Diodes | Arm Width (cm) | Laser Wavelength (nm) |
| SPEC 2D-S | 10 | 128 | 6.3 | 785 |
| SPEC HVPS-3 | 150 | 128 | 16.25 | 785 |
| DMT CAPS-CIP | 25 | 64 | 10.0 | 658 |
| DMT PIP | 100 | 64 | 26.0 | 658 |
Information from Readme File
All files are in the native raw data format for each instrument, with SPEC format for the 2D-S and HVPS-3, and DMT PADS format for the CAPS-CIP and PIP. Following the usual conventions, SPEC-formatted data have file names baseYYMMDDHHMMSS.2DS[HVPS], and DMT-formatted data have file names Imagefile_YYYYMMDDHHMMSS.CAPS[PIP].
Each simulation contains 60 seconds of a single particle size distribution, starting at midnight (00:00:00) on January 1st, 2010. Particles have been positioned randomly between the arms and across the array of the probe, and their sizes have been defined by maximum dimension from a circle fit. The true air speed is 100 m/s for all simulations.
