1中国地震台网与美国地震台网测定震级的对比(Ⅱ)——面波震级显示文摘采用正交回归方法,利用中国地震局地球物理研究所(IGCEA)和美国地质调查局国家地震信息中心(USGS/NEIC)1983-2004年的观测资料,对这两个机构测定的面波震级进行了系统的比较,得到了中国地震台网与美国地震台网面波震级之间的关系式.结果表明,由于使用的震级计算公式和观测仪器不同,IGCEA测定的面波震级总体上要比NEIC测定的结果偏高0.2级;对于3.5~4.5级的地震,IGCEA测定的震级比NEIC测定的震级偏高0.3级;对于5.0~6.5级的地震,IGCEA偏高0.2级;对于7.0级以上的地震,IGCEA偏高小于0.1级.刘瑞丰 陈运泰 PETER BORMANN 任枭 侯建民 邹立晔 杨辉 2006地震学报2006,28,1:57
2中国地震台网与美国地震台网测定震级的对比(Ⅰ)——体波震级显示文摘采用正交回归的方法,利用中国地震台网和美国地震台网1983—2001年的观测资料, 对中国地震局地球物理研究所(IGCEA)和美国地质调查局国家地震信息中心(NEIC)测定的 体波震级进行了比较.从正交回归得到的结果看,IGCEA测定的体波震级mb与NEIC测定 的体波震级mb不存在系统差.如果以NEIC测定的体波震级为基准,对于3.5~4.5级之间 的地震,IGCEA测定的震级比NEIC测定的震级偏高O.2~O.1级;对于5.O~5.5级之间的 地震,IGCEA与NEIC测定的体波震级没有偏差;对于6.O级以上的地震,IGCEA比NEIC 偏低小于O.2级.而IGCEA测定的体波震级与国际数据中心(IDC)测定的体波震级结果基本 一致.刘瑞丰 陈运泰 Peter Bormann 任枭 侯建民 邹立晔 杨辉 2005地震学报2005,27,6:32
3Growing Operational Use of FY-3 Data in the ECMWF System显示文摘This paper reviews the data quality and impact of observations from the FY-3 satellite series used operationally in the ECMWF system. This includes data from the passive microwave radiometers MWHS-1, MWHS-2 and MWRI, as well as observations from the radio occultation receiver GNOS. Evaluations against background equivalents show that the quality of the observations is broadly comparable to that of similar instruments on other polar-orbiting satellites, even though biases for the passive microwave observations can be somewhat larger and more complex for some channels. An observing system experiment shows that the FY-3 instruments jointly contribute significantly to the forecast skill in the ECMWF system. Positive impact of up to 2% is seen for most variables out to the day-2 forecasts over hemispheric scales, with significant benefits for total column water vapor or for temperature and wind in the stratosphere out to day 4.Niels BORMANN David DUNCAN Stephen ENGLISH Sean HEALY Katrin LONITZ Keyi CHEN Heather LAWRENCE Qifeng LU 2021Advances in Atmospheric Sciences2021,38,8:3

5Assimilation of Feng-Yun-3B Satellite Microwave Humidity Sounder Data over Land显示文摘The ECMWF has been assimilating Feng-Yun-3B(FY-3B) satellite microwave humidity sounder(MWHS) data over ocean in an operational forecasting system since 24 September 2014. It is more difficult, however, to assimilate microwave observations over land and sea ice than over the open ocean due to higher uncertainties in land surface temperature, surface emissivity and less effective cloud screening. We compare approaches in which the emissivity is retrieved dynamically from MWHS channel 1 [150 GHz(vertical polarization)] with the use of an evolving emissivity atlas from 89 GHz observations from the MWHS onboard NOAA and EUMETSAT satellites. The assimilation of the additional data over land improves the fit of short-range forecasts to other observations, notably ATMS(Advanced Technology Microwave Sounder) humidity channels, and the forecast impacts are mainly neutral to slightly positive over the first five days. The forecast impacts are better in boreal summer and the Southern Hemisphere. These results suggest that the techniques tested allow for effective assimilation of MWHS/FY-3B data over land.Keyi CHEN Niels BORMANN Stephen ENGLISH Jiang ZHU 2018Advances in Atmospheric Sciences2018,35,3:2
