title: Master and Landsat-8 simultaneous acquisition datacubes for the quantification of directional anisotropy in Thermal Infra-Red domain

description: ‎ This dataset contains datacubes of simultaneous Landsat-8 and Master<sup>1</sup> data as listed in table 1. Those pairs have been identified by cross-searching Landsat-8 and Master archive for Master flight tracks with a Landsat-8 overpass during the flight. The dataset has been collected and analysed in the following paper: <em>Julien Michel, Olivier Hagolle, Simon J Hook, Jean-Louis Roujean, Philippe Gamet. Quantifying Thermal Infra-Red directional anisotropy using Master and Landsat-8 simultaneous acquisitions. 2023. 〈hal-04073733〉</em> Table 1: List of valid Master and Landsat-8 pairs <strong>Id</strong> <strong>Master track id</strong> <strong>Landsat L2 product id</strong> 1 <code>2013-03-29_18:06:53</code> <code>LC08_L2SP_038037_20130329_20200912_02_T1</code> 2 <code>2013-04-11_18:14:46</code> <code>LC08_L2SP_041036_20130411_20200912_02_T1</code> 3a <code>2013-05-22_18:13:09</code> <code>LC08_L2SP_040036_20130522_20200913_02_T1</code> 3b <code>2013-05-22_18:13:09</code> <code>LC08_L2SP_040037_20130522_20200913_02_T1</code> 4 <code>2013-12-05_18:23:35</code> <code>LC08_L2SP_043035_20131205_20200912_02_T1</code> 5a <code>2014-03-31_18:11:16</code> <code>LC08_L2SP_039035_20140331_20200911_02_T1</code> 5b <code>2014-03-31_18:11:16</code> <code>LC08_L2SP_039036_20140331_20200911_02_T1</code> 6a <code>2014-04-14_18:27:14</code> <code>LC08_L2SP_041036_20140414_20200911_02_T1</code> 6b <code>2014-04-14_18:27:14</code> <code>LC08_L2SP_041037_20140414_20200911_02_T1</code> 7 <code>2014-04-28_18:22:43</code> <code>LC08_L2SP_043035_20140428_20200911_02_T1</code> 8a <code>2014-06-06_18:25:35</code> <code>LC08_L2SP_044033_20140606_20200911_02_T1</code> 8b <code>2014-06-06_18:25:35</code> <code>LC08_L2SP_044034_20140606_20200911_02_T1</code> 9a <code>2014-10-21_18:35:15</code> <code>LC08_L2SP_043034_20141021_20200910_02_T1</code> 9b <code>2014-10-21_18:35:15</code> <code>LC08_L2SP_043035_20141021_20200911_02_T1</code> 10a <code>2015-05-28_18:13:05</code> <code>LC08_L2SP_040036_20150528_20200909_02_T1</code> 10b <code>2015-05-28_18:13:05</code> <code>LC08_L2SP_040037_20150528_20200909_02_T1</code> 11 <code>2018-06-19_18:28:30</code> <code>LC08_L2SP_042034_20180619_20200831_02_T1</code> 12a <code>2021-03-30_18:32:40</code> <code>LC08_L2SP_043033_20210330_20210409_02_T1</code> 12b <code>2021-03-30_18:32:40</code> <code>LC08_L2SP_043034_20210330_20210409_02_T1</code> Variables of interest are resampled on a common UTM grid at 100m.
