Hope you don't consider me to be one of the "deniers." I was only presenting my opinion based on my training and experience as a meteorologist....
The GREET model seems to calculate GHG emissions relatively close to those calculated by Tesla in the linked "Impact Report." From GREET, the GHG...
Thank you for the info. As someone who has fully recovered from COVID-19 (infected in August), I'm not sure if I will need to be vaccinated...
Well, I tested positive for COVID-19, and did everything I could to have avoided it. I'm >65, and was concerned about how I would respond if...
The SST cooling in the equatorial Pacific is becoming quite impressive [IMG]
According to the radar image, the radar at that time was in "vcp215." More on vcp modes is available at NWS JetStream MAX - Doppler Radar Volume...
Agree. According to https://uk-air.defra.gov.uk/assets/documents/reports/cat09/1907101151_20190709_Non_Exhaust_Emissions_typeset_Final.pdf ,...
Here is another look at PN emissions: https://nanoparticles.ch/archive/2019_Czerwinski_PR.pdf
Yes, most of those show high PN emissions @cold start or off-cycle ambient conditions. However, the firsts reference ( Real driving particle...
Yes, here are a few studies regarding PM/PN emissions from PFI engines: Real driving particle number (PN) emissions from China-6 compliant PFI...
Yes. Source-apportionment studies have shown that diesel particulate matter is a relatively minor contributor to ambient PM2.5 in spite of the...
Here are graphics from a CARB report ("California’s Informal Participation In The Particle Measurement Programme (Pmp) Light Duty Inter-Laboratory...
Yes, gasoline engine particles typically are finer. The explanation I've heard though is that diesel engines generally have higher engine-out PM...
Apparently, GPFs are not as efficient as DPF in removing exhaust particles, yet anyway - http://nanoparticles.ch/archive/2019_Czerwinski_PR.pdf
According to Argonne National Laboratory's GREET model ( https://greet.es.anl.gov/ ), the default BEV passenger car (long range) charged with 100%...
