In the previous post, I reviewed approaches for point measurements of precipitation (i.e., rain gauges), talked about the care that must be taken to site well and minimize undercatch, and identified some of the common data sources for rain gauge measurements in the United States. Rain gauges do a great …
In January, I launched the #365climateimpacts project, in which I’ll spend a year tweeting stories of the many ways climate change is impacting people, ecosystems, and the earth; ideas for how to communicate about climate change more effectively; and analyses of technologies and policy proposals that show promise for combatting …
The Watershed Hydrology lab will be out in force for the Geological Society of America annual meeting in Vancouver in October. Over the next few days, we’ll be sharing the abstracts of the work we are presenting there. SENSITIVITY OF PRECIPITATION ISOTOPE METEORIC WATER LINES AND SEASONAL SIGNALS TO SAMPLING …
Next week, the Watershed Hydrology Lab will be well represented at the CUAHSI 2014 Biennial Colloquium. We’ll be presenting four posters, so here come the abstracts… Stormwater control measures modify event-based stream temperature dynamics in urbanized headwaters Grace Garner1, Anne Jefferson2*, Sara McMillan3, Colin Bell4 and David M. Hannah1 1School …
This work is being conducted by undergraduate lab member, Allison Reynolds. Allison presented her work as part of the CUAHSI/USGS Virtual Workshop on applications of laser specs to hydrology and biogeochemistry. From that workshop, she will have an extended abstract published in a USGS open file report, and her poster …
Radar is increasingly used to measure precipitation in hydrologic science applications. It’s handy because it can be both frequent and areally distributed. This NWS newsletter does a great job of going over the basics of how weather radar can be used to derive rainfall rates and totals. This page gives a …
Cross-posted at Highly Allochthonous It’s been quite a week. My home in northeastern Ohio got off lightly from “Superstorm” Sandy, compared to places closer to the Atlantic seaboard and in the Caribbean. But still, over 250,000 people lost power due to high wind, especially in Cuyahoga and Lorain counties along …
Cross-posted at Highly Allochthonous If you live in the eastern 1/3 of the US and you haven’t started paying attention to Hurricane Sandy, today is THE day. This odd late-season storm is going to hit the northeastern and mid-Atlantic coast hard, having already stormed across the Caribbean, killing at least …
Cross-posted at Highly Allochthonous Even though we all think of the freezing point of water as 0 °C, very pure water remains a liquid until about -40 °C. Water crystallizes to ice in the presence of tiny nucleation particles in the atmosphere. These particles can be sea spray, soot, dust …
