DCMEX Cloud top height estimates from stationary ground camera timelapse photos
Description
This data is part of the Deep Convective Microphysics Experiment (DCMEX) project.
Code from https://zenodo.org/records/18939170 attempts to automatically detect the cloud base and top height from timelapse photography using:
- Optical cloud depth to estimate the distance to max cloud thickness
- OpenCV edge detection to estimate the cloud top location in the image
- Thin Lens equations to use lens information, pixel information and distance information to give a pitch-corrected cloud top height estimate
This dataset is the archived results of the automated processing, containing a dataset of image pairs (images with cloud top heights labelled, paired with satellite-derived optical depth distance estimate plots. The pixel information, calculated distances to cloud and estimated cloud top and cloud base height are saved as a time series for each day in CSVs in the results folder
All the methodology is outlined in the DCMEX wiki. Follow-up work was done automatically, calculating cloud top heights from aircraft-mounted cameras in DCMEX2. Results from these works have been used in the UNRISK CDT training on comparing field observations and models https://doi.org/10.5281/zenodo.19921147
