Her development of a grid in the late 1950s wherein she gently inscribed penciled lines over subtle fields of color marked a turning point in the history of abstract painting and established the geometric and spatial language that she continued to refine over the ensuing decades.
With her gentle inscriptions of penciled lines on subdued fields of wash and color, Martin established a geometric and spatial language that she would refine and reinterpret over ensuing decades.
«This study investigates past sea level reconstruction (over 1950 — 2003) based on tide gauge records and EOF spatial patterns from different 2 - D fields.
Although teleconnections are best defined over a grid, simple indices based on a few key station locations remain attractive as the series can often be carried back in time long before complete gridded fields were available (see Section 3.6.4, Figure 3.31); the disadvantage is increased noise from the reduced spatial sampling.
[T] he basis of the results are correlations over a very restricted set of locations (predominantly western Europe, Japan and the USA) which project strongly onto naturally occurring patterns of climate variability, or are with fields with significant amounts of spatial auto - correlation.
New gridded daily wind fields from Metop / ASCAT scatterometer retrievals are produced in near real - time over global ocean with a spatial resolution of 0.25 °.
If we are trying to estimate the average temperature over a wide area like the U.S. or the Globe, it is advisable to use gridding or some more complicated form of spatial interpolation to assure that our results are representative of the underlying temperature field.
For example, the regional model Im working on, will get the temperature correct for the entire field (averaged over 30 years) but the trend is the wrong direction and its a disaster in the spatial dimension
These range from simple averaging of regional data and scaling of the resulting series so that its mean and standard deviation match those of the observed record over some period of overlap (Jones et al., 1998; Crowley and Lowery, 2000), to complex climate field reconstruction, where large - scale modes of spatial climate variability are linked to patterns of variability in the proxy network via a multivariate transfer function that explicitly provides estimates of the spatio - temporal changes in past temperatures, and from which large - scale average temperature changes are derived by averaging the climate estimates across the required region (Mann et al., 1998; Rutherford et al., 2003, 2005).
The records document that the Laschamp Excursion was characterized locally by (1) declination changes of ± 120 °, (2) inclination changes of more than 140 °, (3) ~ 1200 - year oscillations in both inclination and declination, (4) near 90 ° out - of - phase relationships between inclinations and declinations that produced two clockwise loops in directions and virtual geomagnetic poles (VGPs) followed by a counterclockwise loop, (5) excursional VGPs during both intervals of clockwise looping, (6) magnetic field intensities less than 10 % of normal that persisted for almost 2000 years, (7) marked similarity in excursional directions over ~ 5000 km spatial scale length, and (8) secular variation rates comparable to historic field behavior but persisting in sign for hundreds of years.
Lukovich et al. (Centre for Earth Observation Science, U. of Manitoba); 4.4 to 4.5; Heuristic - Dynamics The absence of a strong and persistent sea level pressure high over the Beaufort in July together with the absence of spatial homogeneity in the springtime sea ice drift fields suggest that continued sea ice decline will be an artifact of increased temperatures and thermodynamic forcing rather than the considerable dynamical contributions seen in summer of 2007.
Conducted spatial analysis for wind, solar, and transmission line projects for engineering layouts involving up to 1,000 miles of field survey, 3 years of redesign and over 1,000 cultural resources.
