Selected micrometeorological and soil data from the Manaus ZF2 K34 eddy covariance tower for the 2015/16 El Niño event

The K34 tower site (2.609 S, 60.209 W, 130 masl), located within the Tropical Silviculture Experimental Station (EEST, also known as ZF2) research station, in an area of undisturbed tropical forest (Araújo et al. 2002). It features long term measurements using micrometeorological, eddy covariance, and soil instrumentation, among others. This dataset covers January 2012 to December 2017, and includes air temperature (TA, ℃) and air relative humidity (RH, %), measured with thermohygrometers (HC2S3, Campbell Scientific, Logan, UT, USA) deployed above the canopy at the top of the tower (at 51.1 m height), and net radiation (NETRAD, W m-2) using an NR-LITE sensor (Kipp & Zonen, Delft, Netherlands), also at the top of the tower (at 35.0 m above the canopy). The soil moisture data included here is from a soil profile located approximately 12 m from the tower, and covers the period between February 2015 and September 2016. Volumetric soil water content (SWC, m3 m-3) measurements used Water Content Reflectometers (CS655 Campbell Scientific, Logan, UT, USA) at six depths: 10 cm, 20 cm, 30 cm, 40 cm, 60 cm, and 100 cm. Data are included in .csv files, and the text file ZF2-K34_Tower_headers.txt provides descriptions of data file headers.

K34塔观测点（南纬2.609°，西经60.209°，海拔130米）位于热带造林实验站（Tropical Silviculture Experimental Station，简称EEST，又称ZF2）研究站内的一片未受干扰的热带森林区域（Araújo等，2002）。该站点开展了长期观测，使用的仪器包括微气象仪、涡动协方差仪和土壤仪器等。本数据集涵盖2012年1月至2017年12月的观测数据，包括：塔冠层上方（高度51.1米）使用温湿度计（HC2S3型，Campbell Scientific公司，美国犹他州洛根市）测量的空气温度（TA，℃）和相对湿度（RH，%）；以及塔冠层上方（高度35.0米）使用NR-LITE传感器（Kipp & Zonen公司，荷兰代尔夫特市）测量的净辐射（NETRAD，W/m²）。本数据集包含的土壤湿度数据来自塔旁约12米处的土壤剖面，时间范围为2015年2月至2016年9月。体积土壤含水量（SWC，m³/m³）的测量采用CS655型水分反射仪（Campbell Scientific公司，美国犹他州洛根市），测量深度为10厘米、20厘米、30厘米、40厘米、60厘米和100厘米。数据存储于.csv文件中，文本文件ZF2-K34_Tower_headers.txt提供了数据文件头的说明信息。
