Water vapour plays in important role in the energy budget of the atmosphere. Despite many years of study there are still considerable uncertainties both in the measurement of water vapour and it’s representation in radiation models. In an attempt to reduce these uncertainties two field experiments in differing atmospheres were conducted in 1999. The results from a tropical atmosphere and a sub-...

Water vapour concentrations are measured using the optical absorption of a Zeeman-split emission line of an argon discharge lamp. When a longitudinal magnetic field of the proper magnitude is used to split the emission line, two components of opposite circular polarization are produced: one coincident, and one off-resonance with respect to a water vapour absorption line at 10 687.36 cm−1. Diffe...

Reductions in fossil fuel use and increases in system efficiency are required to make space heating more environmentally benign. Ground loop heat pumps offer an alternative heating solution that is more environmentally benign than conventional methods. Past studies of these heat pumps have usually focused on basic system arrangements, but new advanced systems are being developed. Here, energy a...

Luminescent cyclometalated complex [Pt(L)py]+ (1) immobilised in Nafion film exhibits a solvatochromic shift in emission maximum from 530 to 650 nm upon immersion in ethanol but no effect is detected with aprotic organic solvents, whereas the emission of the [Pt(L)]+ luminophore anchored in silica materials shows a blue shift from approximately 665 to 550 nm upon exposure to pentane vapour but ...

This paper shows a tool chain of a set of ready-touse tools and libraries that enables the dynamic real-time simulation of vapour compression cycles. A new approach for calculation of fluid properties and numeric efficient component models are applied. As an Hardware in the Loop application a vapour compression cycle is exported to Scale -RT [5] using SimulationX [11] and connected to a hardwar...

Referee: This article describes an updated retrieval method to obtain water vapour columns in polar regions from the MHS and AMSU-B instruments. The improvements to current methods are described and the new method tested against synthetic and real data. The new method involves using a-priori information and iterating a radiative transfer model to optimise the optical depth profile by scaling th...
