ABSTRACT:

This resource contains accompanying stream water and rainwater chemistry data (dissolved P, K, and Ca) reported in the manuscript "Rapid response of stream dissolved phosphorus concentrations to wildfire smoke" by Fernandez et al. The dataset spans an ~ 1.5 year period from April 2022 to October 2023 and captures an unprecedented smoke period that took place in the region during the summer of 2023.

File is provided in ".xlsx" format. The excel file tabs are organized with a summary page ("Contents") followed by supplementary tables (S1, S2, S3, and S4) that correspond to dataset type (Streamwaters, Rainwaters, AirQuality, and Meteorology). Goechemical data were generated by this study whereas stream discharge, PM2.5 aerosol concentrations, and meteorlogical data were obtained from the USGS National Water Information Service (NWIS, https://waterdata.usgs.gov/usa/nwis), PurpleAir (https://api.purpleair.com/), and Northeast Regional Climate Center (NRCC) CLIMOD-2 (http://climod2.nrcc.cornell.edu/).

Additional information for how stream discharge was determined for ungauged Cascadilla Creek can be found in the manuscript in "Online Methods" under sub-heading "Stream discharge".

ABSTRACT:

This resource contains accompanying stream water chemistry data (major cations, anions, DOC, Silicon, Germanium, and Silicon stable isotopes) presented in "Resiliency of silica export signatures when low order streams are subject to storm events" by Fernandez et al. The datasets represent seven storm events from six different catchments across the US, Canada, and France as part of an international cross-CZO collaboration supported through SAVI (Science Across Virtual Institutes).

Files are provided in ".csv" format and are organized both with respect to individual sites (listed below) and as bulk metadata (designated 'AllSites' ).

CZO sites and storm events investigated for this study (site specific csv file name identifier is provided inside the brackets [ ] ):
[LaJara] - La Jara Creek, Jemez CZO (New Mexico, USA) - March to Late May 2017 snowmelt event
[ProvidenceCreekP303] - Providence Creek Subcatchment P303, Southern Sierra CZO (California, USA) - January 2018 rain event
[ElderCreek] - Elder Creek, Eel River CZO (California, USA) - January 2017 rain event
[Sapine ] - Sapine Creek, OZCAR (Mont Lozère, FRA) - October 2016 rain event and long term monthly sampling from 2013-2015
[QuiockCreek] - Quiock Creek, OZCAR (Basse-Terre, Guadeloupe, FRA) - October 2015 rain event
[KwakshuaWatershed708] - Kwakshua Watershed 708, Hakai Institute (Calvert Island, British Columbia, CAN) - two rain events, September and October 2017

Site-specific lithology and associated chemical compositions used in calculations for fSi (proxy for fraction of Si remaining in solution) are provided in 'bedrock_compositions.xlsx'. Refer to the manuscript for further details.
