The ASTER dataset for EUREC4A
<p>The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is mounted aboard Terra, a polar-orbiting satellite in a descending Sun-synchronous orbit with an Equator crossing time of 10:30 local solar time. ASTER recorded 412 images of trade cumulus cloud fields east of Barbados in support of the EUREC4A field campaign between 11 January and 15 February (<a href="https://doi.org/10.5194/essd-13-4067-2021">Stevens et al., 2021</a>). While the original L1B data is publicly available from <a href="https://doi.org/10.5067/ASTER/AST_L1B.003">NASA EOSDIS</a>, the dataset here includes processed physical variables and geolocation information.<br> Only bands from the visual near-infrared (VNIR) and thermal infrared (TIR) radiometers are available since 2007. The files therefore include L1B radiances from VNIR and TIR bands, together with geolocation information, a cloud mask, and cloud top height estimates. The cloud mask is derived following a method described by <a href="https://doi.org/10.5194/amt-9-5869- 2016">Werner et al., 2016</a>. The cloud top height estimates are derived through an infrared-window approach following <a href="https://doi.org/10.1175/JAMC‐D‐11‐0203.1">Baum et al., 2012</a>. Code for processing the original ASTER L1B data is available in the Python package <a href="https://doi.org/10.5281/zenodo.5786028"><em>typhon</em> version 0.9.0</a>, subpackage <em>cloudmask</em>.</p>

ASTER elevation data for the SAFE Project
<b>Description: </b><p>These files contain processed data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument, providing 1 arc second (~30 metre) resolution elevation data across the research areas used in the SAFE Project.<br><br>The ASTER data used in these datasets was collected by the NASA TERRA satellite. Although it is freely downloadable, ASTER data downloaded for a project <b>should not be redistributed outside of that project</b>. Accordingly, these data should <b>only</b> be used for research carried out at the SAFE Project.<br><br> These files combine four panes of ASTER data to cover the SAFE sampling region and carry out some simple geoprocessing to produce a single output files. Details of the geoprocessing can be found here: <a href="https://www.safeproject.net/dokuwiki/safe_gis/aster">https://www.safeproject.net/dokuwiki/safe_gis/aster</a>. In general, SRTM data is preferable for most use cases at SAFE, (see <a href="https://zenodo.org/record/3490488">https://zenodo.org/record/3490488</a>) but is provided here for comparison.</p><p><b>Project: </b>This dataset was collected as part of the following SAFE research project: <a href="https://www.safeproject.net/projects/project_view/1"><b>SAFE CORE DATA</b></a></p><p><b>XML metadata: </b>GEMINI compliant metadata for this dataset is available <a href="https://www.safeproject.net/datasets/xml_metadata?id=3491956">here</a></p><p><b>Files: </b>This dataset consists of 2 files: SAFE_Aster_metadata.xlsx, ASTER_WGS84_raw.tif</p><p><b>SAFE_Aster_metadata.xlsx</b></p><p>This file only contains metadata for the files below</p><p><b>ASTER_WGS84_raw.tif</b></p><p>Description: ASTER elevation data in WGS84 geotiff</p><p><b>Date range: </b>2010-10-01 to 2019-10-01</p><p><b>Latitudinal extent: </b>4.0000 to 6.0000</p><p><b>Longitudinal extent: </b>116.0000 to 118.0000</p>
