Positron scattering and annihilation from the hydrogen molecule at zero energy [PDF]
, 2009 The confined variational method is used to generate a basis of correlated gaussians to describe the interaction region wave function for positron scattering from the H$_2$ molecule. The scattering length was $\approx -2.7$ $a_0$ while the zero energy $Z_{

Ship-based lidar measurements for validating ASCAT-derived and ERA5 offshore wind profiles [PDF]
Atmospheric Measurement TechniquesThe accurate characterisation of offshore wind resources is crucial for the efficient planning and design of wind energy projects. However, the scarcity of in situ observations in marine environments requires the exploration of alternative and reliable ...

MSWEP : 3-hourly 0.25° global gridded precipitation (1979-2015) by merging gauge, satellite, and reanalysis data [PDF]
, 2016 Current global precipitation (P) datasets do not take full advantage of the complementary nature of satellite and reanalysis data. Here, we present Multi-Source Weighted-Ensemble Precipitation (MSWEP) version 1.1, a global P dataset for the period 1979 ...

Validation and Cross-Validation Methods for ASCAT
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017 The advanced scatterometer (ASCAT) is a fan beam scatterometer carried on board the Metop series of satellites. Its primary objective is to measure ocean backscatter for the retrieval of ocean wind vectors. Two ASCAT instruments (ASCAT-A and ASCAT-B) are operational and are independently calibrated using a number of ground-based transponders. The first

On the assimilation of ASCAT winds
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016 In contrast with scatterometer wind data, Numerical Weather Prediction (NWP) models do not well resolve the mesoscale sea surface wind flow under increased wind variability conditions, such as in the vicinity of low-pressure centers, frontal lines, and moist convection.

Automated Steel Cleanliness Analysis Tool (ASCAT) [PDF]
, 2005 The objective of this study was to develop the Automated Steel Cleanliness Analysis Tool (ASCATTM) to permit steelmakers to evaluate the quality of the steel through the analysis of individual inclusions. By characterizing individual inclusions, determinations can be made as to the cleanliness of the steel.
