The IASI/Metop-B HCOOH ANNI v4 product

This dataset comprises the version 4 of the HCOOH product retrieved from IASI/Metop-B between July 2022 and June 2023, using the Artificial Neural Network for IASI (ANNI) version 4 retrieval scheme. Each day is represented by a .nc file. For detailed information on the HCOOH product, please refer to Franco et al. (2018) "A General Framework for Global Retrievals of Trace Gases From IASI: Application to Methanol, Formic Acid, and PAN" (JGR, https://doi.org/10.1029/2018JD029633) and for a description of the ANNI v4 retrievals, please consult Clarisse et al. (2023) "The IASI NH3 version 4 product: averaging kernels and improved consistency" (AMT, https://doi.org/10.5194/amt-16-5009-2023). Prior to using this dataset, we recommend reaching out to the main developers Bruno Franco ([e-mail]) and Lieven Clarisse ([e-mail]) for guidance and information on more recent product versions.本数据集包含2022年7月至2023年6月期间，从IASI/Metop-B卫星载荷获取的、采用适用于IASI的人工神经网络反演方案（ANNI）第4版反演得到的甲酸（HCOOH）第4版产品。每日数据集以单个.nc格式文件存储。如需了解该甲酸产品的详细信息，请参阅Franco等人2018年发表于《Journal of Geophysical Research》（JGR）的论文"A General Framework for Global Retrievals of Trace Gases From IASI: Application to Methanol, Formic Acid, and PAN"（DOI: 10.1029/2018JD029633）；若需了解ANNI v4反演方案的具体说明，请参考Clarisse等人2023年发表于《Atmospheric Measurement Techniques》（AMT）的论文"The IASI NH3 version 4 product: averaging kernels and improved consistency"（DOI: 10.5194/amt-16-5009-2023）。在使用本数据集前，建议您先联系主要开发者Bruno Franco（邮箱：[e-mail]）与Lieven Clarisse（邮箱：[e-mail]）以获取使用指导及最新版本产品的相关信息。
