Description: OPERA Level-2 Radiometric Terrain Corrected (RTC) SAR Backscatter products in VH polarization generated from Sentinel-1 (S1) SAR imagery, processed by the OPERA project at JPL. Values for the VH (cross-polarized) polarization are generally driven by volume scattering, with more complex volume scatterers (such as dense vegetation) returning higher backscatter values. Surface water generally appears very dark, as it is predominantly a surface scatterer; most returns remain in the primary polarization. diff --git a/image_services/opera/metadata/metadata_text/OPERA_RTC_CA_VV_metadata.txt b/image_services/opera/metadata/metadata_text/OPERA_RTC_CA_VV_metadata.txt index f611d99b..af002d60 100644 --- a/image_services/opera/metadata/metadata_text/OPERA_RTC_CA_VV_metadata.txt +++ b/image_services/opera/metadata/metadata_text/OPERA_RTC_CA_VV_metadata.txt @@ -5,7 +5,7 @@ Tags: ASF, Alaska Satellite Facility, Synthetic Aperture Radar, SAR, Sentinel-1, OPERA, Radiometric Terrain Correction, RTC Summary: -OPERA Level-2 Radiometric Terrain Corrected (RTC) SAR Backscatter products for an area in Northern California from 08-Oct-2023 to 04-Dec-2023 in VV polarization generated from Sentinel-1 SAR imagery, processed by the OPERA project at JPL. +OPERA Level-2 Radiometric Terrain Corrected (RTC) SAR Backscatter products for an area in Northern California from 08-Oct-2023 to 04-Dec-2023 in VV polarization generated from Sentinel-1 (S1) SAR imagery, processed by the OPERA project at JPL. Description: OPERA Level-2 Radiometric Terrain Corrected (RTC) SAR Backscatter products in VV polarization generated from Sentinel-1 (S1) SAR imagery, processed by the OPERA project at JPL. Values for the VV polarization are commonly driven by surface roughness and/or soil moisture, with rougher surfaces and higher soil moisture returning higher backscatter values. Surface water appears very dark under calm conditions, as the signal bounces off the surface away from the sensor.
