    Applicability Evaluation of China’s First Generation of Global Land Surface Reanalysis (CRA40/Land) Air Temperature and Precipitation Products in China Mainland by Caixia WANG, Anning HUANG, Peng ZHENG, Kai LIU, Min HOU

    Published 2022-10-01
    “…The applicability of first-generation of Chinese land surface reanalysis dataset (CRA40/Land) has been evaluated with the observations from 2231 national meteorological stations and further compared with the ERA5 and CFSR datasets in terms of the spatial and temporal variations of monthly air temperature and precipitation.Triangulation linear interpolation is used to interpolate grid data into stations, and station data into grid.The China mainland is divided into four regions according to the stations distribution and topographic features.The bias, standard deviation ratio, root mean square error (RMSE), correlation coefficient and model skill of the 3 reanalysis datasets in four regions are computed to compare the accuracy and evaluate the application.The comparative results suggest that the CRA40, ERA5 and CFSR datasets can reproduce similar spatio-temporal distribution patterns of the monthly air temperature and precipitation with the observations in Mainland of China.In particular, they all show much better performance in the eastern China than in western China and in winter than in summer.For the monthly air temperature, the mean errors of the 3 reanalysis datasets are generally within 2 ℃, with slightly better performance for the CRA40 and ERA5 datasets.For the monthly precipitation, the errors of the 3 reanalysis datasets show large differences, the CRA40 performs the best and shows the highest applicability over Mainland of China among the 3 datasets.…”

    Exploring vaginal microbiome: from traditional methods to metagenomic next-generation sequencing—a systematic review by Siying Liu, Yuxin Chen, Kunxiu Zhang, Dan Tang, Ji Zhang, Yuxin Wang, Jiaqi Zhao, Diyan Li, Tao Wang

    Published 2025-08-01
    “…Several factors can affect data quality, including sampling procedures, contamination issues, and PCR amplification errors. We suggest implementing third-generation sequencing (TGS) to address these challenges to enhance reproducibility and read length, utilizing single-molecule sequencing (SMS) to eliminate PCR amplification-related errors, and integrating multiple analytical approaches to provide comprehensive insights. …”
