This repository is home to the NASA SnowEx Snow Pit processing scripts and blank field template and digital data sheets.
There are four main directories organized by SnowEx field campaign year: SnowEx2017, SnowEx2020, SnowEx2021, and SnowEx2023, hereinafter referred to as S17, S20, S21, and S23.
Within each directory there is the main script that produces the parameter files (_density.csv, _temperature.csv, _lwc.csv, _stratigraphy.csv, etc) from the electronic snow pit sheets.
| Year | Campaign Type | Measurement Focus |
|---|---|---|
| 2017 | IOP | Colorado, focused on multiple instruments in a forest gradient. |
| 2020 | IOP, TS | Western U.S focused on Time Series of L-band InSAR, active/passive microwave for SWE and thermal IR for snow surface temp. |
| 2021 | TS | Western U.S, continued Time Series of L-band InSAR, also addressed prairie & snow albedo questions. |
| 2023 | IOP | Alaska Tundra & Boreal forest, focused on addressing SWE/snow depth and albedo objectives. |
IOP = Intense Observation Period (~2-3 week, daily observations); TS = Time Series (~3-5 month winter, weekly observations)
