    PALSAR Products Information

    Products Information ALOS PALSAR products are available via the new ESA PALSAR data On-The-Fly (OTF) processing and dissemination system. The service currently provides access from ESA's archive to the following PALSAR L1 high-resolution data products. Note that there are differences between JAXA and ESA ALOS PALSAR CEOS product formats. The ESA L1.1 is in zero-Doppler and not beam coordinates. The signal data record headers also have a different format - the ESA "L1:1" products are basically identical to L1.5 products, aside from slant range projection/pixel dimensions. Instrument mode Product Type Processing Level Description JAXA Processing Level Equivalent Fine Beam Single polarisation FBS_RAW_0P Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene. 1.0 FBS_GDH_1P Ground range Detected, Normal resolution product Was 1.5 but superseded by ESA CEOS product FBS_GEC_1P Geocoded product Was 1.5 but superseded by ESA CEOS product FBS_SLC_1P Slant range single look complex product Was 1.1 but superseded by ESA CEOS product Fine Beam Double polarisation FBD_RAW_0P Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene. 1.0 FBD_GDH_1P Ground range Detected, Normal resolution product Was 1.5 but superseded by ESA CEOS product FBD_GEC_1P Geocoded product Was 1.5 but superseded by ESA CEOS product FBD_SLC_1P Slant range single look complex product Was 1.1 but superseded by ESA CEOS product Polarimetry mode (4 polarisation) PLR_RAW_0P Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene. 1.0 PLR_GDH_1P Ground range Detected, Normal resolution product Was 1.5 but superseded by ESA CEOS product PLR_GEC_1P Geocoded product Was 1.5 but superseded by ESA CEOS product PLR_SLC_1P Slant range single look complex product Was 1.1 but superseded by ESA CEOS product ScanSAR Burst mode 1 WB1_RAW_0P Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene. 1 WB1_GDH_1P Ground range Detected, Normal resolution product Was 1.5 but superseded by ESA CEOS product WB1_GEC_1P Geocoded product Was 1.5 but superseded by ESA CEOS product ALOS products follow the standard CEOS format convention. The dataset contains all ESA acquisitions over the ADEN zone (Europe, Africa and the Middle East) plus some worldwide products received from JAXA. Further information on ADEN zones can be found in this technical note. Products Availability The PALSAR OTF system provides direct online access to ESA's ALOS PALSAR archive for ESA registered users, without the need to interface with the ESA Order Desk. Data are accessible through the ALOS PALSAR On-The-Fly web interface If users do not have an EO-SSO account on Earth Online, it is possible to create an account following the registration instructions.

    VFM Overview

    ... current that enables the sensor to detect minute deviations from the zero field. Noise on the instrument is only a few Picotesla while VFM provides a long-term stability in the sub Nanotesla range. The VFM is an analogue instrument and as such is subject to temporal changes due to radiation and the aging effect of electronics. The effects are only significant in the bias and linear scale parameters of the characterization; hence these parameters are estimated daily through a comparison of the VFM output with the Absolute Scalar Magnetometer output.
