FTIR formic acid (HCOOH) groundbased remote sensing at Porto Velho from instrument BIRA.IASB004

FTIR formic acid (HCOOH) total columns and low vertical resolution profile data at Porto Velho (Brazil). Details on the FTIR retrieval technique can be found in a paper describing our Reunion Island data (https://doi.org/10.5194/acp-12-10367-2012). The retrieval parameters used in the present HCOOH time-series at Porto Velho are following this latter study. Data users are kindly invited to collaborate to ensure a proper use of the FTIR data (e.g. appropriate use of the averaging kernels).

The guidelines in the GEOMS documentation should be used to select the latest version of a data file in case files have overlapping dates.

采用傅里叶变换红外光谱（FTIR）获取的巴西波尔图韦柳（Porto Velho）地区甲酸（HCOOH）总柱浓度及低垂直分辨率廓线数据。有关FTIR反演技术的详细说明，可参阅一篇描述我们留尼汪岛观测数据的研究论文（https://doi.org/10.5194/acp-12-10367-2012）。本次波尔图韦柳地区甲酸时间序列研究所采用的反演参数，均遵循该研究的设定。恳请数据使用者协同配合，以确保FTIR数据的规范使用（例如合理使用平均核函数）。

若存在日期重叠的数据文件，请参照GEOMS文档中的指南选取最新版本的数据文件。
