“…Previous studies have found that a temperature gradient across the molecular boundary layer (top few micrometres of water surface) exists at the air-water interface, such that T skin is systematically cooler (typically by a few tenths of a degree) than the water several centimetres below (Robinson et al, 1984;Wick et al, 1996;Horrocks et al, 2003). Water skin temperature values derived from CNR1 measurements of upwelling long-wave radiation are representative of the temperature of the top few micrometres of the water surface (Donlon et al, 2002).…”

Accurate methods of latent heat flux quantification are essential for water management and for use in hydrological and meteorological models. Currently the effect of small lakes in most numerical weather prediction modelling systems is either entirely ignored or crudely parameterized. In order to test methods for modelling hourly latent heat flux from small water bodies, this study compares results from several modelling approaches to values measured by the eddy covariance method at an agricultural reservoir in southeast Queensland, Australia.Mass transfer estimates of LE calculated using the theoretical mass transfer model and using the Tanny et al.

“…Previous studies demonstrated the satellite-based SST data are less accurate than the in-situ data due to the complexity of the oceanic and atmospheric conditions (Robinson, Wells and Charnock, 1984;Brown, Brown and Evans, 1985;Minnett, 1991) although the errors in the satellite-based SSTs were found to vary regionally and temporally (Wick, Emery and Schluessel, 1992). In this study we compared the satellite-based operational SST analysis to the shipbased in-situ SST measurements made by the Atlantic Zone Monitoring Program (AZMP) over the eastern Canadian shelf.…”

Abstract:The satellite-based operational sea surface temperature (SST) was compared to the ship-based in-situ SSTs established by the Atlantic Zone Monitoring Program (AZMP) over the eastern Canadian shelf (ECS) for a 3-year analysis period (2005)(2006)(2007). Two sets of operational SST analyses were considered in this study, with one set produced by the Canadian Meteorological Centre (CMC) and the other produced by the National Centers for Environmental Prediction (NCEP). The comparative study indicated that there was no appreciable systematic difference between the CMC and NCEP SST analyses over the ECS. The root mean squared difference (RMSD) between the AZMP ship-based in-situ SSTs and the satellite-based STT analyses over the ECS was about 1.0°C, without any obvious seasonal or geographic trend. The RMSDs were relatively larger over the outer flank of the Grand Banks than the other regions of the ECS, mainly due to dynamically complicated circulation and hydrographic conditions over this shelf break area associated with the Labrador Current.

“…Conventionally, validation of satellite SSTs is undertaken using "bulk" temperature measurements from sensors in the upper 1 m or so of the water column whereas the 702 upwelling radiance sensed by the satellite is actually from a very thin surface "skin" (less than a millimetre in thickness). The temperature difference between the surface skin and the subsurface 704 layer is typically of order 0.3°C (Robinson et al 1984) and so very accurate measurements of both are required. The bulk temperature measurements in this study were made using the surface 706 bucket and the SDL profiler while the "skin" temperature was measured using a radiometer (see McAtee et al, this volume).…”

A 27-month study of the water properties across the continental shelf off Perth, Western 2 Australia (the "Hillarys Transect") has provided the first systematic inter-disciplinary climatology of the physical, chemical, optical and biological cycles across the shelf. This paper 4 describes the main features of the seasonal and cross-shelf variability of the physical oceanography and chemistry, while companion papers discuss some of the links between the 6 biology and physics of the region.The oceanography is dominated by the seasonally-varying Leeuwin Current flowing 8 southwards along the shelf break and outer shelf, and the northwards inshore Capes Current which is driven by the net southerly wind stress between about October and March (the austral 10 summer). As a result of the poleward boundary current, there is no large-scale upwelling comparable with the Humboldt and Benguela Current systems. Water temperature and salinity in 12 the shallow coastal waters are largely influenced by air-sea heat flux processes, while advection plays a more important role along the outer shelf; as a consequence, seasonal variations in the 14 inshore temperature and salinity are much larger than those offshore. Cross-shelf exchange of water and plankton is effected by (1) large-scale meandering of the Leeuwin Current, (2) 16 horizontal mixing as tongues of Leeuwin Current water penetrate across the shelf, (3) cascading of high-density coastal water offshore along the seabed, and (4) sporadic summer upwelling onto 18 the outer shelf (including the wake effect north of Rottnest Island).Nutrient and chlorophyll concentrations are low in comparison with other typical west 20 coast situations. While there is some indication of a seasonal cycle, the relatively short sampling period and high patchiness have precluded definitive patterns being described and longer-term 22 sampling may be required to resolve this.The effects of smaller-scale temperature and chlorophyll variability on satellite remote 24 sensing measurements (both "within-pixel" and "between pixel") in these coastal waters have been quantified using the underway (horizontal) and profile (vertical) data from the surveys. The 26 3 project has demonstrated the great potential of using remote sensing information for regular monitoring of the Western Australian continental shelf waters provided that adequate in situ 28 validation measurements are also undertaken.
