Separate names with a comma.
The emission standards are really beside the point anyway. My comments in Post #149 were to disagree with a previous comment that light-duty...
The thing of it is is that NMOG and NOx are combined into one standard for both Tier 3 and LEV3. I'm not sure if EPA will continue to break out...
Bob, I generally use Dieselnet for regulatory standards. DieselNet: Diesel Exhaust Emission Standards The U.S. is currently transitioning from...
Actually, it was a 2013 BMW X5 35d that was "real world" tested, if you're referring to the ICCT/WVU report, as confirmed by one of the WVU...
Yes, I used the CARB cert, except for PM (PM is listed at 0.00 g/mi on the CARB cert; 0.0002 g/mi on the EPA cert). The 328d CARB cert is...
Okay, I'll disagree. :) The 2017 BMW 328d has one of the lowest, if not the lowest, overall emission profile of any 2017 vehicle officially...
Bob, It appears a surface front/boundary is providing additional lift in the northwestern quadrant of Matthew, inducing heavier precip than what...
As of today's (Saturday's) 15Z run, the SREF (mesoscale ensemble model) has Matthew going essentially north through the Bahamas by 06Z Wednesday....
I generally agree, but I'm not as impressed with atmospheric models, at least not NWP (weather) models. Several years ago, the most recent...
Yes, and that's one of the problems with NWP (weather) models - there are some subgrid-scale atmospheric processes the can't be resolved and...
Record 15-minute rainfall rate in the U.S. is 3.95" (10 cm)... [IMG] What is the Most Rain to Ever Fall in One Minute or One Hour? | Weather...
Oh, okay, 'toof. Thanks! Learn something new everyday!
What does "table=head" do, Bob?
Here are the well-to-pump emissions and energy consumption of E10 gasoline and ULS diesel fuel according to Argonne National Laboratory's GREET...
Like this Bob? Edit: For some reason, I can't get the link to post. Here's the citation... Naomi Zimmerman, Jonathan M. Wang, Cheol-Heon...
I'm responding to the comment about particulates, not NOx. NOx is the pollutant that was affected by VW's cheat mode. Among many other...
Strongly disagree with the "20 times as many particulates [as petrol cars]" assertion. It's the other way around, if anything, especially with...
Wonder when Europe will become equally as concerned about PM/PN emissions from gassers? Source: Badshah, H., Kittelson, D., and Northrop, W.,...
To add a little more confusion to the issue, it appears VW is doing well emissions-wise with some of its TDIs in Europe. Tests reveal VW's...
It's been known for decades that ambient ground-level ozone levels tend to increase on weekends, when ozone precursor emissions decrease, relative...
