***General Introduction***
This dataset contains data collected during a field campaign at Yellowstone National Park, under permit #YELL-2022-SCI-8098
It is being made public both to act as supplementary data for publications and in order for other researchers to use this data in their work.
The data in this data set was collected in Yellowstone National Park in July 2022, at two sites: Terrace Spring and Poison Spring at Mammoth Terrace.
This research project was supported by a Waksman-Busch seed grant and the 4TU Federation HTSF research programm (Plantenna project). Instrumentation construction was supported by the US Department of Energy Office of Basic Energy Sciences, Division of Chemical Sciences, Geosciences, and Biosciences, grant DE347FG02-10ER16195.

***Purpose of the measurement campaign***
The purpose of these experiments was to study metabolic adaptation of a photosynthetic angiosperm (Prunella vulgaris) to extreme CO2 levels in Yellowstone.

***Description of the data in this data set***
The data included in this dataset has been obtained using a Fast Repetition Rate Fluorescence protocol. The data has been organized as text files per fluorescence experiment. 
The files follow the nomenclature system: Site, sample number, CO2 exposure, sample sequence
Site: TSP = Terrace Spring, VJPP = Poison Spring
CO2 Exposure: A for ambient CO2 exposure (400ppm) , C for high CO2 exposure (6000ppm).
Sample sequence: sequential experiments were conducted on the same sample, with 4 minutes dark time in between experiments.
