The Layer is called 'NDVI' in my Configurater Utility.\r\n\r\nThe NDVI images are completely downloaded. However, only 3 from 5 images have a content, while the other 2 are empty. Because it is a time range and I get no error message, what is the most convenient way to avoid that issue. I also tried `wcs.get_data(redownload=True)`, but this did not solve the problem.\r\n\r\n`mybbox = [47.24, 11.05, 47.61, 11.55]    \r\nBBOX = BBox(bbox=mybbox, crs=CRS.WGS84)\r\n\r\nwcs = WcsRequest(data_folder=outdir,\r\n                              layer='NDVI',\r\n                              bbox=BBOX,\r\n                              time=('2017-08-15', '2017-08-25'),\r\n                              resx='20m', resy='20m',\r\n                              image_format=MimeType.TIFF_d32f,\r\n                              instance_id=INSTANCE_ID)\r\n\r\nwcs_img = wcs.get_data(save_data=True)`"}}
