Here's a more formal study of lubricity of biodiesel blends......
There was a study conducted several years ago comparing the lubricity of additives to ULSD, including biodiesel (B2). According to that study, B2...
Based on the latest run of the European model (ECMWF - 12Z 26 Oct.), the storm is projected to move into New Jersey by around 12Z 30 Oct. The...
Yes, I agree. There is a new NWP model (NAM-WRF) that has a spatial (horizontal grid) resolution of 4 km over the CONUS (as opposed to the ~60...
Doug - from your link in your last post... That's news to me (I'm a recently-retired operation meteorologist from the U.S. National Weather...
austingreen - I encourage you to download the latest version of Argonne National Laboratory's GREET model (GREET1_2012). It's available for...
I was actually referring to "conventional" emissions, not CO2. However, if you notice in the link you provided, at the bottom of the page......
Agree with austingreen. A report issued recently by DOE (EIA, “Light-Duty Diesel Vehicles: Market Issues and Potential Energy and Emissions...
The EPA emission factors are domestic emissions. Here's a reproduction of the upstream EPA emission factors table by stages (note the...
As far as how much benefit a diesel engine gets from "hybridization" compared to a gasoline engine, an Argonne National Laboratory study suggests...
Actually, the MB E350 BlueTec comes very close to hitting SULEV (It even hits the SULEV NOx standard of 0.02 g/mile). It's just slightly higher...
For what it's worth, MB claims the diesel-hybrid version of its E-class produces 26% lower CO2 emissions (23% lower life-cycle) than the straight...
Yes, I agree. It can also be expected that disorganized diurnal convection ("pulse" storms, i.e., typical scattered afternoon thunderstorm cells...
That should NOT be an expected outcome of AGW, at least with the polar amplification premise of IPCC. Tornadoes should tend to decrease in...
It's my experience that SST oscillations and upper-level meteorological features (e.g., persistent upper-level ridges/troughs) are linked in time...
I agree, but I'm not confident that atmospheric models will ever be able to forecast synoptic-scale features months in advance. Droughts are...
As a former NOAA (NWS) employee, I'm glad that Mr. Karl stopped short of linking extreme severe weather events (e.g., tornado outbreaks, derechos,...
Another interesting anecdote similar to Bob's. I retired as an operational meteorologist from the National Weather Service at the beginning of...
Sure, just wanted to be clear. Since the nitrogen in NOx is in its oxidized state, the challenge to reduce the NOx to elemental nitrogen has...
Actually, scr (and also NOx storage catalysts which are used on the VW Jetta TDI) converts oxides of nitrogen (NOx = NO + NO2) into mostly...
