Terrestrial Carbon (TerraC) Information System

TerraC is dedicated to: (i) advance terrestrial carbon science through sharing of carbon and environmental data; (ii) facilitate environmental synthesis; and (iii) enhance collaboration among researchers, scientists, and extension specialists through shared resources. TerraC offers tools to upload, store, manage, query, analyze, and download data characterizing terrestrial carbon dynamics from various sources, including soils, plants/biomass, atmosphere, water, and whole ecosystems. It was developed by Dr. Grunwald’s research team.

What is Pedometrics?

Pedometrics = pedos [soil] and metron [measurement]

“Pedometrics” (term coined by A.B. McBratney) is a neologism, which stems from the Greek words pedos [soil] and metron [measurement]. It is formed and used analogously to other applied statistical fields such as biometrics, psychometrics, econometrics etc. (see Preface of Geoderma, 1994: 62). Pedometrics is defined as:

“the application of mathematical and statistical methods for the quantitative modeling of soils, with the purpose of analyzing its distribution, properties and behavior”

Trends in soil science sub-disciplines and subjects between 1967 and 2001. The ordinate is the percentage of papers in Geoderma (source A.. E. Hartemink et al., 2001; Geoderma, 100, pp. 217-268).


Contemporary pedometrics topics:

  • Analysis and modeling of spatial and temporal variation of soil properties
  • Digital soil mapping
  • Error propagation
  • Multiscale data integration
  • Soil-landscape modeling
  • SCORPAN or CLORPT based modeling
  • Soil pattern analysis
  • Quantitative soil classification algorithms
  • Pedogenic simulation modeling
  • Design and evaluation of sampling schemes
  • Soil sensors
  • Diffuse reflectance spectroscopy for soil mapping
  • Remote sensing supported soil mapping
  • and more

World Soil Day 2015

The 68th United Nations General Assembly has designated 5th of December as World Soil Day and declared 2015 as the International Year of Soils.
