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

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 “Unprecedented observation of hourly rock glacier velocity with Ground-Based SAR” (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 survey1 (from 09/08/2018 to 18/08/2018), and survey2 (from 13/09/2018 to 03/10/2018). TS_August_moving.csv: includes the survey 1 displacement data of moving points on the rock glacier. TS_August_stable.csv: includes the survey 1 displacement data of stable points outside the rock glacier. TS_September_moving.csv: includes the survey 2 displacement data of moving points on the rock glacier. TS_ September_stable.csv: includes the survey 2 displacement data on stable points outside the rock glacier. Each *.csv file contains the following fields: “displacement”: cumulative displacement (mm); “pointName”: name of point where the time series are computed, as displayed in figure 3; “time”: time of acquisition, in day/month-hour:minute format; “velocity”: velocity (mm/hour); “X” and “Y”: 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 Polygon_RG_Lazaun.shp. 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 raster_survey_1.tif and raster_survey_2.tif, are completed by two files of the same name with the colored overlay (raster_survey_1.lyr and raster_survey_2.lyr). The two velocity maps obtained from survey1 and survey2 are also provided as complete georeferenced figures in geotiff format and named figure_survey_1.tif and figure_survey_2.tif. All the geospatial data are provided in the EPSG 32632 spatial reference. AIR TEMPERATURE 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 day/month/year hour:minute 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;
