Geoscientific Information
JERS-1/SAR L0 SAR Data is obtained from the SAR sensor onboard JERS-1 and produced by National Space Development Agency of Japan (NASDA).JERS-1 which mounts SAR is Sun-synchronous sub-recurrent Orbit satellite launched on February 11, 1992. This dataset includes Unprocessed Signal Data Product Data. Data which has undergone absolutely no correction is recorded. Data required for higher level correction is ALOS recorded. It is same as the unprocessed data of other sensors prepared at the EOC. The provided format is CEOS.

JERS-1/OPS L2 Visible and Near Infrared Radiometer Data is obtained from the OPS sensor onboard JERS-1 and produced by National Space Development Agency of Japan (NASDA).JERS-1, which is equipped with OPS is Sun-synchronous sub-recurrent orbit satellite launched on February 11, 1992. The dataset includes System Corrected Image Products. No radiometric correction is applied at the moment due to the lack of the calibration coefficients. Spatial Resolution is 18m x 24m. Map projection is UTM, SOM and PS. The provided format is CEOS.No explicit product version. Level 0â4 data is available.

The JERS-1 Optical System (OPS) is composed of a Very Near Infrared Radiometer (VNIR) and a Short Wave Infrared Radiometer (SWIR). The instrument has 8 observable spectral bands from visible to short wave infrared. Data acquired by ESA ground stations The JERS-1 OPS products are available in GeoTIFF format. These products are available only for the VNIR sensor. All four bands are corrected. The correction consists in a vertical and horizontal destriping, the radiometry values are expanded from the range [0,63] to the range [0,255]. No geometrical correction is applied on level 1. The pixel size of approximately 18 x 24.2 metres for raw data is newly dimensioned to 18 x 18 metres for System Corrected data using a cubic convolution algorithm. Disclaimer: Cloud coverage for JERS OPS products has not been computed using an algorithm. The cloud cover assignment was performed manually by operators at the acquisition stations. Due to missing attitude information, the Nadir looking band (band 3) and the corresponding forward looking band (band 4) are not well coregistered, resulting in some accuracy limitations. The quality control was not performed systematically for each frame. A subset of the entire JERS Optical dataset was selected and manually checked. As a result of this, users may occasionally encounter issues with some of the individual products.

The JSA_SLC_1P product is comparable to the ESA SLC/IMS images generated for Envisat ASAR and ERS SAR instruments. It is a slant-range projected complex image in zero-Doppler SAR coordinates. The data is sampled in natural units of time in range and along track, with the range pixel spacing corresponding to the reciprocal of the platform ADC rate and the along track spacing to the reciprocal of the PRF. Data is processed to an unweighted Doppler bandwidth of 1000Hz, without sidelobe reduction. The product is suitable for interferometric, calibration and quality analysis applications. Data acquired by ESA ground stations

The JSA_PRI_1P product is comparable to the ESA PRI/IMP images generated for Envisat ASAR and ERS SAR instruments. It is a ground range projected detected image in zero-Doppler SAR coordinates, with a 12.5 metre pixel spacing. It has four overlapping looks in Doppler covering a total bandwidth of 1000Hz, with each look covering a 300Hz bandwidth. Sidelobe reduction is applied to achieve a nominal PSLR of less than -21dB. The image is not geocoded, and terrain distortion (foreshortening and layover) has not been removed. Data acquired by ESA ground stations.
