英文摘要Atmospheric ammonia (NH3) plays an important role in the formation of fine particulate matter, leading to
severe environmental degradation and human health issues. In this work, ground-based Fourier transform
infrared spectrometry (FTIR) observations are used to obtain the total columns of atmospheric NH3 at Hefei,
China, from December 2016 to December 2020. After the presentation of the retrieval algorithm and uncertainty
budget, we perform a spatio-temporal analysis of the dataset. Over the four years, NH3 columns have been
increasing by 15.82% (2017-2018), 3.83% (2018-2019) and 3.68% (2019-2020). A clear seasonal cycle is
observed, with the largest surface concentrations (12.93 & PLUSMN; 6.40 ppb) observed in June to August, and the lowest
(4.08 & PLUSMN; 2.66 ppb) in November to January. The diurnal cycles of NH3 exhibit increased morning and afternoon
concentrations. Interpretation of the diurnal cycles is difficult, however, the absence of a peak during rush hours,
and the absence of correlation with CO and NO2 suggest that agriculture and not traffic is the main source of NH3
at Hefei. The polar plots of NH3 columns with wind and back trajectories of air masses calculated by the HYSPLIT model confirmed that agriculture was the dominant source of ammonia in four seasons, while urban anthro-pogenic emissions contributed to the high level of NH3 in summer over the Hefei site. We end this paper with a short validation exercise of NH3 columns retrieved from measurements of the IASI satellite data with the FTIR measurements over Hefei. Correlation coefficients (R) between the two datasets are 0.79 and 0.75 for IASI-A and IASI-B, with the slope of 0.96 and 1.10, respectively. The mean difference is-3.44 x 1015 and-3.96 x 1015 molec cm-2, with standard deviation of 7.16 x 1015 and 8.10 x 1015 molec cm-2, respectively. These results demonstrate the IASI and FTIR data, over Hefei, are in broad agreement.
