title: Nutrients and phytoplankton pigments concentrations at the Sud Bastia station (Corsica Channel, Corsica)

description: This dataset contains time series (2012 - 2022) of monthly nutrient and HPLC phytoplankton pigment concentrations measured at the Sud Bastia station. The station is located in the Corsica Channel over the 40 m isobath.
The analyzed nutrients (in uM) are nitrate (NO3), nitrite (NO2), ammonia (NH4) and silicate (Si(OH)4). 
The measured pigments (in ng L-1) include chlorophyll a (chl a), divinyl chlorophyll a (DVchl a), total chlorophyll a (Tchl a), peridinin (Peri), 19'-butanoyloxyfucoxanthin (Buta), fucoxanthin (Fuco), neoxanthin (Neo), prasinoxanthin (Prasino), violaxanthin (Viola), 19'-hexanoyloxyfucoxanthin (19’HF), alloxanthin (Allo), zeaxanthin (Zea), lutein (Lutein) and total chlorophyll b (Tchl b). Sampling and analysis methods are described in Goffart et al. (2015).
These data contribute to characterize seasonal patterns of phytoplankton biomass and composition in a region where very limited information on phytoplankton dynamics is available.

title: Collocated PurpleAir Sensors and T640 Reference Data located at Durango Complex in Phoenix, AZ May 2019: Case Study Demonstrating EPA's Performance Targets and sensorstoolkit Python Code Library

description: Three PurpleAir sensors were collocated with a T640x reference monitor at the Durango Complex Air Quality Monitoring Station in Phoenix, Arizona in May 2019.  Both instruments measured PM2.5 and PM10 and this collocation exercise was done to better understand how the sensor data compared to the reference data and what data cleaning and correcting would need to be applied to the sensor data to make these two dataset more comparable.  These data files contain the raw data from this experiment at 1 minute and 20 second time resolution for the sensor data and 1 hour time resolution for the reference monitor data.  Data provided courtesy of USEPA and our project partners Maricopa County Air Quality Department.
