README for Leg 4 MOSAiC ASD data

Each event corresponds to an albedo transect or set of observations. Folder should contain: 
- raw .asd files (instrument-specific format)
- preliminary processed .txt of asd wavelength files (directly corresponding to .asd files)
- processed .csv of albedos
- .xlsx of metadata (for each position: ASD file numbers, photo number, snow or pond depths, notes) 
- folder of photos from each measurement location, as referenced in metadata file

Contact for python (.ipynb) codes to quickly read in and plot data, and compare points across days
