摘要

摘要将2019年10月至2020年9月COSMIC-2与ERA5和探空数据的压力、温度和比湿度曲线进行了比较。结果表明，COSMIC-2气压和比湿度廓线在对流层下层精度和稳定性较差。d - var解有效地提高了对流层温度参数的精度。3个参数在一个气候年内具有较高的精度，但在夏季的具体湿度廓线有轻微的季节波动。此外，COSMIC-2在赤道地区的比湿度数据与探空和ERA5的一致性较低。作者感谢UCAR(大学大气研究公司)提供COSMIC-2剖面数据和怀俄明大学提供无线电探空数据。感谢欧洲中期气象预报中心(ECMWF)提供ERA5再分析产品。本研究在山东大学威海超级计算中心的超级计算系统上进行了数值计算。披露声明作者未报告潜在的利益冲突。数据可用性声明COSMIC-2配置文件数据可从https://data.cosmic.ucar.edu/gnss-ro/cosmic2/nrt/level2/下载。无线电探空数据可从http://weather.uwyo.edu/upperair/sounding.html下载。ERA5再分析产品可从https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5/.Additional信息下载。本研究由辽宁省医生创业基金资助。[2021-BS-275]，辽宁省高等学校科学研究项目[LJKMZ20220673]，精密测量科学技术创新研究院大地测量与地球动力学国家重点实验室[SKLGED2023-3-2];精密测量科学技术创新研究院大地测量与地球动力学国家重点实验室资助的课题。

Comparison of pressure, temperature and specific humidity from COSMIC-2 with radiosonde and ERA5

ABSTRACTPressure, temperature and specific humidity profiles from COSMIC-2 are compared with those from ERA5 and radiosonde data from October 2019 to September 2020. The results demonstrate that COSMIC-2 pressure and specific humidity profiles show relatively poor accuracy and stability in the lower troposphere. The 1D-Var solution effectively improves the accuracy of temperature parameters in the troposphere. Three parameters show high accuracy over one climatological year, but show slight seasonal fluctuations, especially for the specific humidity profiles in summer. Furthermore, COSMIC-2 specific humidity data show low consistency with radiosonde and ERA5 in the equatorial region.KEYWORDS: COSMIC-2ERA5radiosonde1D-Var AcknowledgementsThe authors would like to thank the UCAR (University Corporation for Atmospheric Research) for providing COSMIC-2 profiles data and University of Wyoming for providing radiosonde data. The ECMWF (European Centre for Medium-Range Meteorological Weather Forecasts) is appreciated for providing ERA5 reanalysis products.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
