Description

Tools for researchers is a set of 16 browser-based tools for soil and environmental analysis:

  • Profiles and mapping: a profile harmoniser (depth splines), pedodiversity indices, variogram fitting and kriging, model evaluation, and sampling density.
  • Water: van Genuchten curve fitting, a comparison of water-retention pedotransfer functions, and hydrologic soil group with curve-number runoff.
  • Energy and climate: soil temperature waves, a bare-soil energy balance, FAO-56 evapotranspiration and crop water use, seasonal frost depth, and day length and solar radiation.
  • Soil properties: texture class (USDA, European and Australian triangles), soil carbon stocks including equivalent soil mass, and Munsell colour conversion and matching.

Each tool implements published methods, shows its working, and cites the original method references, so the result can be traced and reported. Everything runs in the browser and no data are sent or stored. Live version: https://rafiki.earth/tools.html
