The North Wyke Farm Platform: Fine Resolution (15-minute) Meteorological Data
The North Wyke Farm Platform (NWFP) was established in 2010 to study and improve grassland livestock production at the farm-scale. The NWFP uses a combination of environmental sensors, routine field and lab-based measurements, and detailed management records to monitor livestock and crop production, emissions to water, emissions to air, soil health, and biodiversity. The rich NWFP datasets help researchers to evaluate the effectiveness of different grassland (and arable) farming systems, which in turn, contributes to the development of sustainable, resilient and net zero land management strategies. This document serves as a user guide to the meteorological data (MET) captured at a 15-minute temporal resolution from the North Wyke Farm Platform (NWFP). The guide gives details of the instrumentation, sensor calibration and data collection and is associated with other dedicated user guides that detail the design, establishment and development of the NWFP, and the quality control process of datasets

Erupting Dwarf Novae in the Large Magellanic Cloud
We report the first likely detections of erupting Dwarf Novae (DN) in an
external galaxy: the Large Magellanic Cloud. Six candidates were isolated from
approximately a million stars observed every second night over 11 nights with
the CTIO 8K x 8K Mosaic2 CCD imager. Artificial dwarf nova and completeness
tests suggest that we are seeing only the brightest of the LMC DN, probably SS
Cygni-like CVs, but possibly SU UMa-type cataclysmics undergoing
superoutbursts. We derive crude but useful limits on the LMC DN surface
density, and on the number of DN in the LMC. Many thousands of cataclysmic
variables in the Magellanic Clouds can be discovered and characterized with 8
meter class telescopes.Comment: Accepted for publication in AJ, 28 pages, 9 figures total, Figures 1
