(annual mean PM2.5, highest occurring 6-monthly mean of daily maximum hourly ozone, crop-growing season mean daytime ozone). For the evaluation of arbitrary emission scenarios, the stored sensitivities are linearly extrapolated using an appropriate scaling factor, thus by-passing computationally ...
(version 13.0.2) and perform 23 sets of conventional, forward-running simulations for September 1stto December 31stfor each year between 1997 and 2019, where monthly fire emissions are available. September is discarded due to model spin-up, and only October to November are considered for the ...
Unprecedented decreases of almost −40 μg m−3 in bimonthly mean PM2·5 concentrations were observed in the areas most affected by COVID-19 (figure 1). In Europe, the mean reduction in PM2·5 concentrations during the lockdown period (from Feb 21, with Italy's first restrictive ...
The journey from Port Harcourt to Lagos by road can be particularly very stressful. This is especially true due to the bad state of some portions of road linking the two cities. Thousands of Nigerians transit between the two cities on a monthly basis but there’s still much left to be do...

or commercial property. There are many different types of AC systems. With that being said, we’re able to recognize that some may be more energy efficient for your facility enabling a decrease in monthly power costs. This is especially important if you’re operating a large commercial ...
32, which offers both annual and monthly mean concentrations for 1998–2019, with global coverage and at 0.01-degree resolution (Fig. 6). The dataset is constructed by combining Aerosol Optical Depth satellite retrievals from the NASA MODIS, MISR, and SeaWIFS instruments with the GEOS-Chem ...
