The measurement sites were approximately distributed to cover the study area, and SM was measured within 0 to 10 cm depth with time-domain reflectometry (TDR) at hourly time-step from March to November 2012. TDR and frequency-domain reflectometry (FDR) sensors are the most commonly used techniques to measure soil water content . The TDR measures the propagation time of an

Intercomparison of different "absolute" instruments

Considering the differences between the various applied measuring techniques, fair agreement of the obtained concentration data was observed. The TSI-condensation nuclei counter agrees closely with the TSI-aerosol electrometer, however, it can be regarded as an "absolute" instrument only for concentrations below 10 3 cm-3.

Statistical downscaling of global climate models (GCMs) allows researchers to study local climate change effects decades into the future. A wide range of statistical models have been applied to downscaling GCMs but recent advances in machine learning have not been explored. In this paper, we compare four fundamental statistical methods, Bias Correction Spatial Disaggregation (BCSD), Ordinary ...

Both the uncompacted, and the propanol‐compacted particles, were size‐selected 2 times: (1) within an electrostatic classifier that was operated subsequent to the propanol compaction step (propanol‐compacted particles), or subsequent to a bypass around the propanol compaction step (uncompacted particles), and (2) within an electrostatic classifier operated downstream of the thermal

Floods represent the most critical natural hazard for many countries and their frequency appears to be increasing in recent times. The legal constraints of public administrators and the growing interest of private companies (e.g., insurance companies) in identifying the areas exposed to the flood risk, is determining the necessity of developing new tools for the risk classification over large ...

Methods for monitoring particulate concentrations

2013-2-6  • Intercomparison trials between the European reference method and various other methods, including the TEOM, are being carried out in the UK. As an interim measure, a default scaling factor (also known as correction factor) of 1.3 is currently applied to all TEOM PM 10 data in the UK national networks in an attempt to account for these losses.

AMT - SegCloud: a novel cloud image segmentation

Abstract. Cloud detection and cloud properties have substantial applications in weather forecast, signal attenuation analysis, and other cloud-related fields. Cloud image segmentation is the fundamental and important step in deriving cloud cover. However, traditional segmentation methods rely on low-level visual features of clouds and often fail to achieve satisfactory performance.
