Thomas Merchant developed robust data engineering and analytics workflows for the lterwg-resilience repository, focusing on ecological productivity and climate-risk analyses. He built reproducible R pipelines for preprocessing Konza Patch Burn Graze data, estimating aboveground net primary productivity, and standardizing outputs for downstream reporting. Leveraging R scripting and data wrangling, Thomas integrated site duration and precipitation data across multiple networks, enabling cross-site extreme-event analyses. He also implemented a water-year precipitation covariate pipeline with Google Drive integration and delivered exploratory trend analysis using the Mann-Kendall test. The work demonstrated depth in data cleaning, transformation, and visualization, supporting reproducible, cross-network environmental insights.

Aug 1, 2025In August 2025, delivered a new Exploratory Data Analysis (EDA) workflow for trend analysis using the Mann-Kendall test in lterwg-resilience. The feature downloads relevant data files, analyzes precipitation and ANPP trends, and generates visualizations grouped by site, treatment, and crop to provide actionable insights into environmental changes. The implementation is backed by commit 1ee49b1dd49a523ab5c9bbfb4f6cd3160ecc16ad.

Jul 1, 2025July 2025 monthly summary for lter/lterwg-resilience focusing on feature delivery, impact, and skills demonstrated. Key features delivered: Water Year precipitation covariates generation pipeline (new R script) that downloads data from Google Drive, processes daily precipitation from multiple sites, computes annual water-year precipitation sums and coefficients of variation, and merges with treatment information to produce focal precipitation variables aligned with ANPP data. Major bugs fixed: No major bugs reported this month. Overall impact and accomplishments: Established a reproducible data processing pipeline that provides robust, ANPP-aligned precipitation covariates for resilience analyses, enabling more accurate modeling inputs and downstream analyses; improves data fidelity, alignment across sites, and traceability from data sources to model inputs. Technologies/skills demonstrated: R scripting and data wrangling, cross-site data integration, Google Drive data access, computation of water-year statistics (sums, CV), data merging with treatment metadata, and Git-based version control.

Feb 1, 2025February 2025 performance for lterwg-resilience focused on delivering robust data pipelines and cross-network analytics for ecological productivity estimation and climate-risk insights. Key features delivered include Konza Patch Burn Graze (PBG) data preprocessing and ANPP estimation with CSV outputs and standardized column names/paths, and Site durations integration with precipitation analytics and extremes (LTAR, NutNet, LTER), including EDA plots and data prep for precipitation-extreme analysis. Major bugs fixed: none reported this month; minor reliability improvements were implemented via duration-script refinements and duration data cleanups. Overall impact: improved data readiness for downstream reporting, enabling reproducible ANPP estimates and cross-site duration/extreme analyses, thereby accelerating decision-making for land management and policy. Technologies/skills demonstrated: data wrangling and ETL, Python/R scripting, CSV I/O, cross-network data integration, EDA/visualization, and version-controlled code hygiene.
