Abstract
This study took advantage of a wildfire, natural variation in rainfall, and a controlled rain-shelter experiment to examine the interactions of fire and rain on soil structure and organic matter storage in a coastal sage scrub ecosystem in southern California. The study includes data from 2022-2024. Passive rain shelters were installed in the fall of 2022, and were paired with nearby control plots. The years preceding the study were drier than average, while 2023 was an exceptionally high rainfall year, and 2024 was close to the long-term average. The study includes two areas that burned in a January 2021 wildfire and an adjacent unburned area. For most variables, there are at total of 36 datapoints for each year (3 areas x 2 rainfall treatments x 6 replicates). The datasets include carbon and nitrogen associated with different soil physical fractions, including water stable aggregates, particulate organic matter, mineral associated organic matter, and soluble pools. Additionally, soil water content was measured at three depths at 15 minute intervals in each plot. This project was funded by NSF grant 2154746.

Description of the data and file structure
The study includes data from 2022-2024 from a coastal sage scrub ecosystem in southern California. Passive rain shelters (diverting 66% of rainfall) were installed in the fall of 2022, and were paired with nearby control plots. The years preceding the study were drier than average, while 2023 was an exceptionally high rainfall year, and 2024 was close to the long-term average. The study includes two areas that burned in a January 2021 wildfire (A and B) and an adjacent unburned area (C). Soil samples (25 cm deep) were collected in January 2022 and late spring of 2023 and 2024. For most variables, there are at total of 36 data points for each year (3 areas x 2 rainfall treatments x 6 replicates). The datasets include carbon and nitrogen associated with different soil physical fractions, including water stable aggregates, particulate organic matter, mineral associated organic matter, and soluble pools. Additionally, soil water content was measured at three depths (0-12, 13-25 and 38-50cm) at 15 minute intervals in each plot.

Description: soil volumetric water content (unitless, cm3 H2O cm-3 soil) at three depths from 36 plots collected in water year 2024 (May 2023 to May 2024). Odd numbered plots had rain shelters, even numbered plots were controls with no shelters. Plots 1-12 were in burned zone A, plots 13-24 were in burned zone B, and plots 25-36 were in the unburned zone, C.

Outputs smoothed time courses and yearly summary files. Uses sensortable2.csv, VWC2022recalibrated.csv, VWC2023recalibrated.csv and VWC2024recalibrated.csv files.
File: lmeVWC.R
Description: R code for linear mixed effects (lme) models run on summarized VWC data (vwc_summary2022recalibrated.csv, vwc_summary2023recalibrated.csv, and vwc_summary2024recalibrated.csv files).
File: palwsa_lme22-24.R
Description: R code for lme analysis of soil organic fractions: water stable aggregate C, dissolved organic C (DOC), particulate organic matter (POM), mineral-associated organic matter (MAOM) and total soil C and N for all years of the study, and extractable N data for 2023. Uses soilCNfractions_allyears.csv and extractableN2023.csv files.
File: sandfreewsa.R
Description: R code for lme analysis of sand-free water stable aggregates. Uses sfwsa.csv file.
File: wsa_CvN.R
Description: R code for regression analysis on C- and N-content of water stable aggregates. Uses soilCNfractions_allyears.csv file.
File: cations_JGR.R
Description: R code for
lme analysis of extractable cations. Uses PALcations2022.csv file.
