TherMod

This set of utilities is used to extract temperature profiles and maps from the NCM thermal model (Boyd, 2019). Running the code requires the NCM thermal model, NCM_TemperatureGrids.nc (https://doi.org/10.5066/P935DT1G), and the NCM spatial grid, NCM_SpatialGrid.nc (https://doi.org/10.5066/P9SBQENM). These codes and datasets are part of an effort to produce a three dimensional national crustal mod

GeoFram

This set of utilities is used to extract geologic profiles from the NCM geologic framework (Boyd, 2019). Running the code in either MATLAB or Python requires the NCM geologic framework and related databases, NCM_GeologicFrameworkVolume.nc, NCM_GeologicFrameworkGrids.nc, and NCM_SpatialGrid.nc (https://doi.org/10.5066/P9SBQENM). These data and codes are part of an effort to produce a three dimensio

FLASH-R (Flow-Log Analysis of Single Holes)

FLASH-R (Flow-Log Analysis of Single Holes) is an R app for the analysis of borehole vertical flow logs to estimate fracture (or layer) transmissivities and far-field hydraulic heads. This app is a new version of the FLASH spreadsheet tool by Day-Lewis et al. (2011) . The program is written in R, an open-source environment. All previous features have been retained and new features incorporated i

bbsAssistant: An R package for downloading and handling data and information from the North American Breeding Bird Survey.

This R package contains functions for downloading and munging data from the North American Breeding Bird Survey (BBS) via FTP (Pardieck et al. 2018; J. R. Sauer et al. 2017). This package was created to allow the user to bulk-download the BBS point count and related (e.g., route-level conditions) via FTP, and to quickly subset the data by taxonomic classifications and/or geographical locations.

Electromagnetic Transfer Function File Conversion Utilities (EMTF FCU)

Magnetotelluric impedances and other similar transfer functions are important for geophysical interpretation and for space weather hazards. I helped develop and continue to curate a database known as IRIS EMTF, http://ds.iris.edu/spud/emtf which uses something called EMTF XML format for storing the data. EMTF FCU v4.1 software consists of a set of freely available format conversion tools that can

Floodplain and Channel Evaluation Tool (FACET)

The Floodplain and Evaluation Tool (FACET) is an open-source python tool that maps the floodplain extent and derives reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs).
