RONO2 and HNO3 formation rates from BEARPEX 09

This repository contains data from the BEARPEX09 Field campaign used in Romer et al., 2020 to calculate the formation rates of RONO2 and HNO3. For additional information about the campaign, see the campaign website: https://www.ocf.berkeley.edu/~bearpex/ <br> Reference information for the BEARPEX09 Field Campaign<br> Dates: Jun 15 - Jul 31 2009<br> Location: Blodgett Forest Research Station, Georgetown CA. 38.91 N, -120.66 W<br> Elevation: 1315 m above sea level<br> Campaign website: https://www.ocf.berkeley.edu/~bearpex/ Measurements listed:<br> utc_date: The date and time of the midpoint of the measurements, in UTC time<br> local_solar_time: The local solar time of the midpoint of the measurements, reported in Pacific Standard Time (UTC-08:00)<br> VOCR_hz: The reactivity to OH of all volatile organic compounds (VOCs), defined as the sum of the concentration of all measured VOCs multiplied by their reaction rate with OH. VOCR is reported in s^-1.<br> NO2_ppt: The concentration of NO2, measured in parts per trillion.<br> Total_RONO2_ppt: The concentration of total organic nitrates (=ΣANs = ΣRONO2), measured in parts per trillion. Includes organic nitrates in both the gas and particle phase, but does not include HNO3 or inorganic nitrate ions.<br> Total_HNO3_ppt: The concentration of nitric acid, measured in parts per trillion. Includes both gaseous nitric acid and thermally labile particle phase nitrate ion.<br> alpha_eff: The effective organic nitrate branching ratio. Defined as the yield of RONO2 compounds when an RO2 radical reacts with NO, averaged over all RO2 species. <br> YRO2_eff: The effective yield of RO2 radicals. Defined as the yield of RO2 radicals when a VOC is oxidized by OH, averaged over all VOCs.<br> fNO_eff: The average probability that an RO2 radical will react with NO, instead of being lost through some other pathway.<br> pressure_bar: The pressure at the measurement location, measured in bar.<br> temperature_K: The temperature at the measurement location, measured in Kelvin.本数据集仓库包含Romer等人2020年研究中使用的BEARPEX09野外实验（BEARPEX09 Field Campaign）实测数据，用于计算有机硝酸酯（RONO2）与硝酸（HNO3）的生成速率。如需了解该实验的更多信息，请参见实验官网：https://www.ocf.berkeley.edu/~bearpex/ <br> BEARPEX09野外实验参考信息<br> 日期：2009年6月15日 - 7月31日<br> 地点：美国加利福尼亚州乔治敦布洛杰特森林研究站，坐标38.91 N, -120.66 W<br> 海拔：1315米<br> 实验官网：https://www.ocf.berkeley.edu/~bearpex/ 测量项列表：<br> utc_date：采用协调世界时（UTC）记录的测量中点的日期与时间<br> local_solar_time：测量中点的当地太阳时间，以太平洋标准时间（UTC-08:00）报告<br> VOCR_hz：所有挥发性有机化合物（Volatile Organic Compounds, VOCs）与羟基自由基（Hydroxyl Radical, OH）的反应活性，定义为所有实测VOCs的浓度与其与OH的反应速率的乘积之和，单位为秒的倒数（s^-1）<br> NO2_ppt：二氧化氮（NO2）浓度，单位为万亿分之一（parts per trillion, ppt）<br> Total_RONO2_ppt：总有机硝酸酯浓度（=Σ烷基硝酸酯（ANs）=ΣRONO2），单位为ppt，涵盖气相与颗粒相中的有机硝酸酯，但不包括HNO3或无机硝酸根离子<br> Total_HNO3_ppt：硝酸（HNO3）浓度，单位为ppt，涵盖气态硝酸与热不稳定颗粒相硝酸根离子<br> alpha_eff：有效有机硝酸酯分支比，定义为过氧烷基自由基（RO2）与一氧化氮（NO）反应生成RONO2的产率，针对所有RO2物种取平均值<br> YRO2_eff：有效过氧烷基自由基产率，定义为挥发性有机化合物被OH氧化时生成RO2的产率，针对所有VOCs取平均值<br> fNO_eff：RO2自由基与NO发生反应的平均概率，相较于通过其他路径损失的概率<br> pressure_bar：测量地点的气压，单位为巴（bar）<br> temperature_K：测量地点的温度，单位为开尔文（K）
