“…For example, the National Crop Loss Assessment Network (NCLAN, USA) obtained the M7-based functions using 10-year OTC experiments (Heck et al, 1982;Wang and Mauzerall, 2004). Mills et al (2007) summarized numerous AOT40-based response functions for some crops obtained by several OTC experiments in Europe and the USA.…”

“…The inconsistency may be due to the differences in statistical methods used for deriving the exposure-response functions (Van Dingenen et al, 2009). For example, yield loss by AOT40 is relative to that in the charcoal-filtered (i.e., zero-O 3 ) air treatment , while the yield losses calculated by the M7 models were relative to that at M7 = 0.025 ppmV (Heck et al, 1982). Adding the yield loss (7.8%) at M7 = 0.025 ppmV compared to that at M7 = 0 ppmV, the yield loss estimation using M7 should be equal to 14.1%.…”

“…Another source of uncertainty is that the yield response functions may also vary with different wheat cultivars, plant locations, and other environmental conditions when using the same index (Heck et al, 1982;Wang and Mauzerall, 2004;Zhu et al, 2011;Wang et al, 2012). In addition, functions were obtained from OTC experiments and the indices were obtained from natural ecosystems, which may also result in some uncertainties (Wang et al, 2012).…”

“…Ground-level ozone (O 3 ) is a secondary pollutant with adverse effects on plant growth, photosynthesis, and crop yields (Heck et al, 1982;Cape, 2008;Feng et al, 2008). The O 3 concentration is determined by its photochemical reactions with NO x (NO + NO 2 ) and VOCs (Volatile Organic Compounds) as well as horizontal and vertical large-scale transport (Crutzen et al, 1999;Cape, 2008).…”

“…To quantify these losses, some O 3 exposure/flux-response models have been generated by using OTC or FACE experiments (Heck et al, 1982;Mills et al, 2007;Feng et al, 2012;Wang et al, 2012). Although flux-based indices have advantages over exposure-based indices owing to their linkage to stomatal uptake of plants, there are some practical limitations that hinder their use in current research.…”

Spatially continuous mapping of daily global ozone distribution (2004–2014) with the Aura OMI sensor

et al. 2016

Total ozone data from the Aura Ozone Monitoring Instrument (OMI) play an important role in the monitoring of the spatial distribution and temporal change of total ozone. However, since September 2005, and especially after mid‐2006, due to row anomalies in the OMI instrument, one third to one half of the OMI total ozone data has been missing. In this study, we generate a spatially continuous and daily global total ozone product (2004–2014) by quantitatively reconstructing the level 3 (gridded) total ozone data via a new two‐step method, which takes full advantage of the temporal and spatial correlation characteristics. First, a preliminary prediction is made based on an adaptive weighted temporal fitting method. Residual correction based on an anisotropic kriging method is then proposed to further improve the prediction accuracy. To assess the efficacy of the proposed method, a comparison of different gap filling algorithms through a series of simulated experiments was performed. On this basis, we further evaluated the proposed product with Brewer spectrophotometers' total ozone columns. The evaluation results suggest that the proposed method outperforms the other algorithms, and its product is better able to capture total ozone variation than the MERRA‐2 assimilated ozone product.

The effects of acidic precipitation and ozone on physiological processes in loblolly pine (Pinus taeda L.) were assessed over time to determine dose‐response relationships of cumulative exposure to varying levels of ozone and acid rain in combination. Seedlings of known provenance were grown in open‐top field chambers in a clear‐cut forest site in Duke Forest in the Piedmont of North Carolina and were exposed to pH 5.2 or 3.5 precipitation and several proportional ozone treatments (0.5‐3.0x ambient ozone). No direct effects of acid precipitation on gas exchange and carbon fixation were found. Elevated ozone exposures had strong negative effects on needle abscission and net photosynthesis. Exposure‐response relationships for photosynthesis indicated that a threshold level of approximately 100 ppm·h of cumulative ozone exposure (12‐h summation) had to be reached before significant inhibition occurred. Results suggest that chronic pollutant exposure over the growing season has direct negative effects on carbon fixation in loblolly pine that can significantly reduce long‐term growth potential. Current ambient ozone levels in the southeastern United States could be responsible for an approximate 19% reduction in instantaneous carbon fixation rates in loblolly pine by the end of one growing season. An 80 to 90% decrease in net photosynthesis was found at 2.25 and 3.0x ambient ozone concentrations, levels often found in major cities and surrounding areas in the South.
