description: <strong>ben-ge/ERA-5: BigEarthNet Extended with Geographical and Environmental Data/Environmental Data</strong> M. Mommert, N. Kesseli, J. Hanna, L. Scheibenreif, D. Borth, B. Demir, "ben-ge: Extending BigEarthNet with Geographical and Environmental Data", IEEE International Geoscience and Remote Sensing Symposium, Pasadena, USA, 2023. ben-ge is a multimodal dataset for Earth observation (https://github.com/HSG-AIML/ben-ge) that serves as an extension to the BigEarthNet dataset. ben-ge complements the Sentinel-1/2 data contained in BigEarthNet by providing additional data modalities: * elevation data extracted from the Copernicus Digital Elevation Model GLO-30;<br> * land-use/land-cover data extracted from ESA Worldcover;<br> * climate zone information extracted from Beck et al. 2018;<br> * environmental data concurrent with the Sentinel-1/2 observations from the ERA-5 global reanalysis;<br> * a seasonal encoding. This archive contains the environmental data of ben-ge, which were extracted from the ERA-5 global reanalysis. <br> <strong>Data</strong> Weather data at the time of observation (temperature at 2 m above the ground, relative humidity, wind vectors at 10 m above the ground) are extracted from the ERA-5 global reanalysis (https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-pressure-levels) for the pressure level at the mean elevation of the observed scene and the time of observation (separately queried for Sentinel-1/2 observations). Environmental data are available in the file ben-ge_era-5.csv. For each patch, identified through the Sentinel-2 patch_id or the corresponding Sentinel-1 patch id patch_id_s1, the file contains the following parameters:<br> * atmpressure_level: atmospheric pressure level at which parameters have been queried [mbar]<br> * temperature_s2: temperature 2m above ground at the time of the Sentinel-2 observation [K]<br> * temperature_s1: temperature 2m above ground at the time of the Sentinel-1 observation [K]<br> * wind-u_s2: eastward component of the wind, at a height of 10 meters above the surface of the Earth at the time of the Sentinel-2 observation [m/s]<br> * wind-u_s1: eastward component of the wind, at a height of 10 meters above the surface of the Earth at the time of the Sentinel-1 observation [m/s]<br> * wind-v_s2: northward component of the wind, at a height of 10 meters above the surface of the Earth at the time of the Sentinel-2 observation [m/s]<br> * wind-v_s1: northward component of the wind, at a height of 10 meters above the surface of the Earth at the time of the Sentinel-2 observation [m/s]<br> * relhumidity_s2: relative humidity at the time of the Sentinel-2 observation [%]<br> * relhumidity_s1: relative humidity at the time of the Sentinel-1 observation [%] as extracted from the ERA-5 global reanalysis (https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-pressure-levels) for the patch location. Please see the corresponding documentation for details. Relevant meta data for the ben-ge dataset are compiled in the file ben-ge_meta.csv. This file resides on the root level of this archive and contains the following data for each patch:<br> * patch_id: the Sentinel-2 patch id, which plays a central role for cross-referencing different data modalities for individual patches;<br> * patch_id_s1: the Sentinel-1 patch id for this specific patch;<br> * timestamp_s2: the timestamp for the Sentinel-2 observation;<br> * timestamp_s1: the timestamp for the Sentinel-1 observation;<br> * season_s2: the seasonal encoding (see below) for the time of the Sentinel-2 observation;<br> * season_s1: the seasonal encoding (see below) for the time of the Sentinel-1 observation;<br> * lon: longitude (WGS-84) of the center of the patch [degrees];<br> * lat: latitude (WGS-84) of the center of the patch [degrees];<br> * climatezone: integer value indicating the climate zone based on Beck et al. 2018 (see below for details). <br> <strong>File and directory structure</strong> This archive contains the following directory and file structure: |<br> |--- README (this file)<br> |--- ben-ge_meta.csv (ben-ge meta data)<br> |--- ben-ge_era-5.csv (ben-ge environmental data) To properly conserve the file and directory structure of the ben-ge dataset, please place this archive file on the root level of the ben-ge dataset and then unpack it. Once unpacked, ben-ge/era-5 requires 80 MB of space. Other data modalities from ben-ge (as well as Sentinel-1/2 data as provided by BigEarthNet, https://bigearth.net/#downloads), may be added as required.
