- in the Tibetan Plateau and its neighboring areas. Time series analysis and both ordinary linear regression (OLS) and geographical weighted regression (GWR) of monthly mean air temperature (Ta) with monthly mean land surface temperature (Ts) were conducted. GWR

- An important hypothesis, and the major emphasis of this paper, is that the immediate surface temperature (Ts) at a site is directly correlated with the overlying air temperature (Ta), thus proving to be statistically significant in predicting Ta
- . However, it is also hypothesized that, for the more complex surfaces, microadvection from adjacent land uses reduces the significance of relationships between Ts and Ta. Microadvection is expressed as a diurnally varying phenomenon, related to atmospheric

- The determination of precipitable water vapour using some daily values of surface parameters at Durban
- The amount of water vapour in the atmosphere above a point on the earth's surface may be estimated on a daily basis using a regression equation involving one or more surface parameters at that point. Preliminary results, using data from Durban

- In this paper data from a series of alpine lakes in British Columbia are applied to develop a new method for deriving error estimates for measured sedimentary parameters. Regression surfaces fitted to point values of sediment mass are used to model
- the physically controlled spatial variability of sedimentation. Deviations from these surfaces are assumed to represent remaining unstructured variance, which constitutes a conservative error estimate. The associated gains in precision justify multicore

- to investigate the relationship between climate and soil character across the contiguous United States. Data from 10,661 sample points were analyzed using geographically weighted regression (GWR) models to describe the geography of the relationship between
- A-horizon soil properties and climate. In addition, macroscale soil property surfaces were interpolated from measured point samples visually to assess the validity of the zonal soil concepts. Results suggest many interesting relationships between climate
- and surface soil character.

- Threshold response of small streams to surface coal minig, bitumous coal fields, central Pennsylvania
- Stream response to surface coal mining and reclamation was studied in 29 small watersheds located in the bituminous coal fields of Central Pennsylvania. Observed differences in channel morphology were related to differences in extent of mining
- by means of scatter plots, correlation, cluster analysis and bivariate regression. For streams that have exceeded threshold levels, disequilibrium is demonstrated by a strong, positive correlation between local stream slope and basin area.

- Field work was done at 3 plots on 32° to 46°slopes in the Upper Reventazón river basin. Annual surface runoff and annual inorganic soil loss were evaluated from the pasture and primary forest plots and secondary forest plot. Discussion

- This paper analyses the topographic context of the remaining glaciated areas in the Maladeta Massif (Central Spanish Pyrenees). These ice-covered surfaces have been incorporated into a geographic information system (GIS) in an attempt at correlating
- the presence of ice with a range of topographic variables obtained from a digital elevation model. The use of generalized additive models and binary regression tree models enabled : to quantify the spatial variability in the distribution of glaciers

- The basal temperature of snow (BTS) method was used to predict the distribution of permafrost within a mountainous basin located in the southern Yukon Territory. A modelled BTS surface, based on several hundred measured values, was created within
- a Geographic Information System (GIS) environment using elevation and potential incoming solar radiation as independent variables. The distribution of frozen ground at 200 test sites was compared to the modelled BTS values using logistic regression

- Detachment of road surface soil by flowing water
- The results illustrate that road surfaces behave characteristically in the runoff detachment and sediment delivery process due to the difference in the bulk density and functions of agricultural soils. The soil detachment rate is closely related
- to flow depth, slope gradient and other hydraulic parameters such as shear stress, stream power and unit stream power. Multiple non-linear regression analyses indicate that detachment rates for all roads can be accurately predicted by power functions
- function of flow depth and slope gradient is also recommended to predict detachment rate on the road surfaces.

- Predicting ordinary kriging errors caused by surface roughness and dissectivity
- Digital elevation model ; Geographical information system ; Geostatistics ; Krigeage ; Model ; Mountain ; Regression analysis ; Roughness ; Soil properties
- The aim of this paper is to determine the association of ordinary kriging (OK) estimated errors with the local variability of surface roughness, and to analyse the suitability of probabilistic models for predicting the magnitude of OK errors from
- surface parameters. The results underscore the importance of the role of the local diversity of relief properties in increasing or decreasing the magnitude of interpolation errors. The newly developed dissectivity parameters provide useful information
- for terrain analysis. The study also provides constructive guides to understanding the local variation of interpolation errors and their dependence on surface dissectivity.
