title: Data from GB-SAR measurements on Lazaun rock glacier (Val Senales, South Tyrol, northern Italy)

description: The *.csv files report the kinematic data extracted from the displacement maps obtained from the processing of ground-based SAR measurements of Lazaun rock glacier (Senales Valley, Northern Italy) and presented in the paper <strong><em>“Unprecedented observation of hourly rock glacier velocity with Ground-Based SAR</em></strong><strong><em>”</em></strong> (Bertone et al., 2023, submitted). The data were used to display the time series reported in the paper. The data refer to two field campaigns named <em>survey1</em> (<em>from 09/08/2018 to 18/08/2018</em>), and <em>survey2 </em>(<em>from 13/09/2018 to 03/10/2018</em>). <em>TS_August_moving.cs</em>v: includes the survey 1 displacement data of moving points on the rock glacier. <em>TS_August_stable.csv</em>: includes the survey 1 displacement data of stable points outside the rock glacier. <em>TS_September_moving.csv</em>: includes the survey 2 displacement data of moving points on the rock glacier. <em>TS_ September_stable.csv</em>: includes the survey 2 displacement data on stable points outside the rock glacier. Each *.csv file contains the following fields: “<em>displacement</em>”: cumulative displacement (mm); “<em>pointName</em>”: name of point where the time series are computed, as displayed in figure 3; “<em>time</em>”: time of acquisition, in <em>day</em>/<em>month</em>-<em>hour</em>:<em>minute </em>format; “<em>velocity</em>”: velocity (mm/hour); “<em>X</em>” and “<em>Y</em>”: coordinates of points (EPGS 32632) where the time series were extracted. The polygon representing the area of the Lazaun rock glacier is provided by the shapefile <em>Polygon_RG_Lazaun.shp.</em> The velocity distribution on the Lazaun rock glacier as obtained in suvey1 and survey2 is provided by raster files. The velocities were obtained along the LOS and are in mm/day. The two raster files, named <em>raster_survey_1.tif</em> and <em>raster_survey_2.tif</em>, are completed by two files of the same name with the colored overlay (<em>raster_survey_1.lyr</em> and <em>raster_survey_2.lyr</em>). The two velocity maps obtained from survey1 and survey2 are also provided as complete georeferenced figures in geotiff format and named <em>figure_survey_1.tif</em> and<em> figure_survey_2.tif.</em> All the geospatial data are provided in the EPSG 32632 spatial reference. <strong>AIR TEMPERATURE</strong> The LAZ_AIRT_survey1.csv and LAZ_AIRT_survey2.csv files contain the air temperature measured about 250 m North from the Lazaun rock glacier by a Gemini Tinytag TGP 4020 data logger connected to an external probe installed in a passive radiation shield. The data cover the two GB-SAR field campaigns (survey 1 from 09/08/2018 to 18/08/2018, and survey 2 from 13/09/2018 to 03/10/2018). The csv files contain the following fields: Date: time of acquisition, in <em>day/month/year</em> <em>hour:minute</em> format; Mean: the mean air temperature recorded by the datalogger during the corresponding hour; Maximum: the maximum air temperature recorded by the datalogger during the corresponding hour; Minimum: the minimum air temperature recorded by the datalogger during the corresponding hour;
