A European daily high-resolution gridded data set of surface temperature and precipitation for 1950-2006

, 2008
We present a European land-only daily high-resolution gridded data set for precipitation and minimum, maximum, and mean surface temperature for the period 1950–2006.

Cost-efficient electromagnetic-simulation-driven antenna design using co-Kriging [PDF]

, 2012
A technique for design optimisation of antennas is presented. The approach exploits coarse-discretisation electromagnetic (EM) simulations of the antenna of interest that are used to create its fast initial model (a surrogate) through Kriging. During the

NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part I: Methods

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this work we present the methods of the areal precipitation nowcasting system NowPrecip version 2. In this version a new methodology is introduced, which, although it shares philosophy and techniques with the original methodology of NowPrecip version 1, can be considered as distinct from that.

A review of new methodological applications for co-kriging in Earth Sciences

Boletín Geológico y Minero, 2011
Cokriging is the multivariate geostatistical estimator that has also been used for estimating spatial factors (factorial cokriging) and for estimating the local distribution function (indicator cokriging). Nevertheless, we show here the flexibility that cokriging offers by reviewing four new applications: (i) downscaling cokriging for image sharpening ...

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

A comparison of kriging, co-kriging and kriging combined with regression for spatial interpolation of horizon depth with censored observations

, 1995
The performances of kriging, co-kriging, and kriging combined with regression were compared. These last two methods were applied to improve the interpolation of the soft-layer depth (Dsl), using the bulk soil electrical conductivity as an auxiliary ...

Annual Average Daily Traffic Estimation using Co-kriging

The Journal of The Korea Institute of Intelligent Transport Systems, 2013
Annual average daily traffic (AADT) serves the important basic data in transportation sector. Despite of its importance, AADT is estimated through permanent traffic counts (PTC) at limited locations because of constraints in budget and so on. At most of locations, AADT is estimated using short-term traffic counts (STC).

Co-Kriging-Guided Interpolation for Mapping Forest Aboveground Biomass by Integrating Global Ecosystem Dynamics Investigation and Sentinel-2 Data

Remote Sensing
Mapping wall-to-wall forest aboveground biomass (AGB) at large scales is critical for understanding global climate change and the carbon cycle. In previous studies, a regression-based method was commonly used to map the spatially continuous distribution ...

NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part II: Verification

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this work we present the verification of the NowPrecip precipitation nowcasting systems (version 1 and version 2). Using 3.5 years of data over the period 2020–2023, their performance is compared with PySTEPS and the ICON numerical weather prediction ensemble by computing deterministic and probabilistic metrics.
