Indoor air quality investigation sector E3-02. NILU OR
Abu Dhabi Municipality has chosen the Norwegian Institute for Air Research (NILU) to perform indoor air quality investigation for six buildings in sector E3-02 (one School, one Mosque, one commercial building and three Residential building).
The main goal of this task is to define the main pollutants that could be found in the buildings and to define the status of existing buildings with respect to indoor air quality.
The results of measurements that were conducted at different locations have shown that there was a wide mold growth in the duct of ventilation system due to poor maintenance in all studied buildings, also that carbon dioxide (CO2) and voltaic organic compound (VOC) are considered the main pollutants that could found and affect the indoor air quality in these buildings.
In most of tested locations, the CO2 concentration has exceeded the standard limit, the readings were very high in the school, mosque, and to a lesser extent in commercial building.

Rotational Raman scattering (RRS) causes filling-in of absorption lines in Earth shine spectra. It is routinely accounted for in analysis of UV and visible spectra measured both by satellite and ground-based instruments. RRS is also present at longer wavelengths, however, the magnitude generally decreases with increasing wavelength due to decrease in the scattering cross section. For high-resolution spectral measurements the effect may be noticeable. Depending on the application, RRS thus needs to be quantified and possibly corrected for. Of special interest is the effect of RRS in the O2-A (759-769 nm) and O2-B (686-697 nm) bands. Here, the effect of RRS in these bands is studied for the present and future satellite instruments CarbonSat, FLEX/FLORIS, MERIS and OLCI.
