Carbon, energy, and water flux data from annual and perennial agroecosystems

This dataset contain meteorological and eddy covariance flux data collected at the University of Illinois Energy Farm from 2017 to 2022. Data collected prior to 2017 can be found on the Ameriflux network (https://ameriflux.lbl.gov/) under sitenames UiA, UiB, UiC, and UiD. DOI's for these datasets are included in the related works section. As of 2025, Ameriflux data submissions for 2017 onward (including for new sites UiE, UiF and UiG), are ongoing. While the unpublished data may be accessed here, they have not yet undergone the rigorous Ameriflux QC process. Thus, the Ameriflux-published version should be the ultimate version of record. 
Five experimental plots are represented: 

Maize-soy 1 (US-UiC; MaizeBasalt)
Maize-soy 2 (US-UiG; MaizeCon)
Miscanthus 1 (US-UiB; MiscanthusBasalt)
Miscanthus 2 (US-UiF; MiscanthisControl)
Sorghum (US-UiE; Sorghum)

The files in this dataset are in one of two forms: an Ameriflux-submission ready .csv which follows Ameriflux variable conve..., The experiment was located at the University of Illinois Energy Farm in Urbana, Illinois, USA.  Information on the local climate can be found in previous studies conducted at this site (Miller et al., 2016; Moore et al., 2021, 2022; Zeri et al., 2011). Soils at the site consist of Dana silt loams, Drummer silty clay loams, and Flanagan silt loams, and range from moderately well drained to poorly drained (von Haden et al., 2019). Soil pH ranged from 5.05 to 5.44 (Masters et al., 2016). Soil organic carbon content ranged from 15 to 20 g kg-1 (Kantola et al., 2017). Wind direction is relatively evenly distributed.
The eddy covariance measurement technique, coupled with meteorological measurements, was applied across five bioenergy cropping systems: an annual maize (Zea mays) – maize – soybean (Glycine max) rotation, perennial miscanthus (Miscanthus × giganteus), perennial switchgrass (Panicum virgatum), restored prairie (an assemblage of 32 annual and perennial Illinois-native species..., , # Carbon, energy, and water flux data from annual and perennial agroecosystems

## Description of the data and file structure

These files contain half-hourly, quality-controlled eddy covariance data from the University of Illinois Energy Farm. We emphasize that the preferred dataset of record is the version published on the Ameriflux network ([https://ameriflux.lbl.gov/](https://ameriflux.lbl.gov/)); see Access information section.

The data directory structure is organized by experimental site, with directories labeled by the site name used in the manuscript. Site naming conventions are as follows:

Manuscript name / Ameriflux site name / PyFluxPro site name:
Maize-soy 1 / US-UiC / MaizeBasalt
Maize-soy 2 / US-UiG / MaizeCon
Miscanthus 1 / US-UiB / MiscanthusBasalt
Miscanthus 2 / US-UiF / MiscanthusControl
Sorghum / US-UiE / Sorghum

本数据集收录了2017年至2022年间于伊利诺伊大学能源农场（University of Illinois Energy Farm）采集的气象与涡度协方差通量数据。2017年之前采集的相关数据可在Ameriflux通量网络（Ameriflux，https://ameriflux.lbl.gov/）上获取，对应站点名称为UiA、UiB、UiC及UiD。上述数据集的数字对象唯一标识符（DOI）已列于相关研究章节中。截至2025年，针对2017年及之后的数据（包括新增站点UiE、UiF与UiG）的Ameriflux提交工作仍在进行中。本数据集收录的未发表数据虽可在此获取，但尚未经过严格的Ameriflux质量控制（QC）流程。因此，最终应以Ameriflux平台发布的版本为官方记录版本。

本数据集涵盖5个试验样地：
1. 玉米-大豆轮作样地1（US-UiC；MaizeBasalt）
2. 玉米-大豆轮作样地2（US-UiG；MaizeCon）
3. 芒草样地1（US-UiB；MiscanthusBasalt）
4. 芒草样地2（US-UiF；MiscanthusControl）
5. 高粱样地（US-UiE；Sorghum）

本数据集包含两种格式的文件：一种是符合Ameriflux变量规范、可直接提交至Ameriflux平台的.csv格式文件（原文此处存在截断）。试验场地位于美国伊利诺伊州厄巴纳的伊利诺伊大学能源农场。该站点的当地气候信息可参阅此前在本场地开展的相关研究（Miller等，2016；Moore等，2021、2022；Zeri等，2011）。本场地的土壤类型包括Dana粉砂壤土、Drummer粉质黏壤土及Flanagan粉砂壤土，排水性能从中等良好至较差不等（von Haden等，2019）。土壤pH值介于5.05至5.44之间（Masters等，2016），土壤有机碳含量为15~20 g kg⁻¹（Kantola等，2017）。风向分布相对均匀。

涡度协方差测量技术结合气象观测被应用于5个生物能源种植系统：一年生玉米（Zea mays）-玉米-大豆（Glycine max）轮作系统、多年生芒草（Miscanthus × giganteus）系统、多年生柳枝稷（Panicum virgatum）系统以及恢复草原（由32种伊利诺伊本土一年生和多年生植物组成的群落……）。
