Establishing a national standard method for operational mixing height determination

A Method for Establishing a Support Criterion or Poverty Line

In this paper, a method for establishing a support criterion or poverty line is developed based on Engel’s Law and domestic nutritional values. The support criterion is differentiated across rural and urban areas. An important result is that for 1989, people who spend less than 108,000 Rials annually lie inside the poverty line in urban areas. A further important result is that food should be g...

Establishing and implementing a national 3D Standard in The Netherlands

community consists of almost 600 people coming from over 100 organisations. The activities of the 3D Pilot cover two phases: an explorative phase, carried out between January 2010 and June 2011 and an implementation-oriented phase, finished at the end of 2012. The major achievement of the first phase was the establishment of a national 3D standard. This standard is embedded in a formal informat...

Mixing height for Copenhagen

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract The urban boundary layer (UBL), in comparison with " rural " homogeneous atmospheric boundary layers, is characterised by greatly enhanced mixing, resulting from both the large surface roughness and increased surface heating, and by horizontal heterogene-...

Establishing a national 3D standard compliant to CityGML: good practice of a national 3D SDI

This article describes a research project that realised a national standard for 3D geo-information. The standard was developed as part of a pilot in which more than 65 private, public and scientific organisations collaborated to analyse and push 3D developments in the Netherlands (run between March 2010 and June 2011). The 3D standard was established through several steps. Firstly a comparison ...
