Ramat Hanadiv measurement site is located ~3.5km from the Eastern Mediterranean coast, and it is surrounded by mixed Mediterranean vegetation.  We operate at the site an eddy covariance measurement station, along with air pollutants and complementary meteorological measurements (see below). 

Some interesting findings using measurements at the site: 

 

• PTR-ToF-MS measurements at this site enabled us to point to elevated emission of isoprene and other BVOCs from the Mediterranean Sea (Dayan et al., 2020).

• Eddy covariance measurements at the site indicated that sea and land breezes can enhance nighttime ozone deposition (Li et al., 2018), a phenomenon that was observed up to at least about 60km inland (Li et al., 2019). 

• Relative humidity plays a dominant role in ozone deposition to vegetation under warm and dry conditions in the Eastern Mediterranean while transport of moisture from the sea, under low relative humidity (e.g., 40%) enhanced the ozone deposition rate to vegetation, probably by deposition of sea salt aerosols on the leaf surface (Li et al., 2018; Li et al., 2019).

• Vegetation wetness and BVOC emission synergistically facilitated leaf ozone uptake (Li et al., 2018).

• Emission of NO from elevated emission sources can act to decrease the ozone deposition rate and even lead to upward ozone flux in a vegetated environment, emphasizing the need to account for the NOs' and VOCs' vertical gradient, and/or vertical flux, at high resolution in studies on ozone deposition (Li et al., 2018).
