I-ADOPT Variable Modelling Challenge

Current state of canonical solutions.

Challenge

  • Cloud cover

    The amount of sky estimated to be covered by all cloud types (cloud amount). The estimate is made to the nearest okta (eighth) and is reported on a scale which is essentially one of the nearest eighth, except that figures 0 and 8 on the scale signify a completely clear and cloudy sky, respectively, with consequent adjustment to the adjacent 1 and 7 okta intervals.

  • Coarse woody debris abundance

    CWD abundance per hectare (m2/hectare) is the abundance of CWD measured from all the plots/transects scaled to a hectare (100 x 100 m). They are calculated using the formula (see https://www.sciencedirect.com/science/article/pii/S037811270900783X)

  • Distance to nearest neighbour habitat patch

    This variable is part of the EBV Connectivity of terrestrial ecosystem habitat types and helps to measure the degree of connection of EUNIS habitats within a landscape, in terms of their spatial distribution. https://github.com/EuropaBON/EBV-Descriptions/wiki/Terrestrial-Connectivity-of-terrestrial-ecosystem-habitat-types

  • dose of applied nanomaterial internalised by a specific cell population (or per single cell) - particle number / cell area

    Correlation of dose and response for nanomaterials toxicity assessment requires information on the amount of the applied dose of nanomaterial that has been internalised by a cell population (or per specific cell) and is dependent on a number of factors including the exposure time, the particle density (i.e., whether settling occurs and thus the distribution of particles in the medium is non-homogeneous affecting the local concentration at the cell surface) etc.

  • dose of applied nanomaterial internalised by a specific cell population (or per single cell) -mass per cell area

    Correlation of dose and response for nanomaterials toxicity assessment requires information on the amount of the applied dose of nanomaterial that has been internalised by a cell population (or per specific cell) and is dependent on a number of factors including the exposure time, the particle density (i.e., whether settling occurs and thus the distribution of particles in the medium is non-homogeneous affecting the local concentration at the cell surface) etc.

  • Feral-free enclosure area

    The total area (in ha) of feral-free enclosures. See https://linked.data.gov.au/def/nrm/d936bfd5-d2f9-5107-bbf7-2bd18bbab42b

  • Foliage projective cover in the lower canopy strata

    The proportion of the ground area covered by foliage (or photosynthetic tissue) held in a vertical plane. Foliage Projective Cover is usually expressed as the percentage of ground covered by foliage and can be separated according to vegetation strata.

  • Mass flux of carbon into soil from vegetation due to senescence

    In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. "Vegetation" means any living plants e.g. trees, shrubs, grass. The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. The term "senescence" means loss of living biomass excluding plant death, e.g. leaf drop and other seasonal effects. The term refers to changes in the whole plant and is not confined only to leaf drop.

  • Maximum trunk char height

    Trunk char height is a measure of the extent of fire height above ground which is measured from the base to the highest point of fire occurrence on the tree trunk. Maximum char height is measured at the community level using a 360° sweep at each sampling location.

  • Probablity of occurence of habitat

    Part of terrestrial Ecosystem distribution of terrestrial EUNIS Habitats EBV, probability of occurrence of EUNIS habitats within contiguous spatial units (grid cells of 100x100 m) across the EU over 1 year time. https://github.com/EuropaBON/EBV-Descriptions/wiki/Terrestrial-Ecosystem-distribution-of-terrestrial-EUNIS-Habitats

  • Strike of bedding

    Geographic azimuth (relative to true north) at a point observation location, of a horizontal line contained in a sedimentary rock bedding surface. The bedding surface must not be horizontal; the azimuth is reported such that the dip direction of the inclined bedding is to the right when facing in the azimuth direction.
