Data - Data Description
GHGSat archive and tasking
The following products are made available: Abundance dataset (Level 2): Set of per-pixel abundances (ppb or mol/m2) for a single species, and per-pixel measurement error expressed as a standard deviation for a single site on a single satellite pass. Data format is GeoTIFF (16-bit) or optionally GeoTIFF (32-bit or 64-bit floating point) Concentration Maps (Level 2): High readability pseudocolour map combining surface reflectance, and column density expressed in ppb or mol/m2 for a single species in PNG (optional PDF) format. The relevant abundance dataset is provided as well. Emission Rates (Level 4): Instantaneous emission rate from targeted source estimated using abundance datasets from a single satellite pass and applying dispersion modelling techniques in PDF format. The delivered product includes the emission rate estimate with uncertainty and key dispersion parameters (in CSV format) as well as the abundance dataset used for the emission estimate. The properties of available products are summarised in the table Band(s) / Beam Mode(s) and Polarisation SWIR (1635-1675 nm), multiple bands, unpolarised Spatial Resolution <30 m Scene size 12 km x 12 km Species Measured CH4 Geometric Corrections Radial distortion, perspective projection Radiometric Corrections Detector pixel response, ghosting, spectral response, atmospheric correction including trace gas modelling and surface reflectance Details about the data provision, data access conditions and quota assignment procedure are described in the GHGSat Terms of Applicability.

ICEYE full archive and tasking
ICEYE full archive and new tasking products are available in Strip, Spot, SLEA (Spot Extended Area) and Scan modes, Complex (SLC) and Amplitude (GRD) processing levels: Strip instrument mode: the ground swath is illuminated with a continuous sequence of pulses while the antenna beam is fixed in its orientation. This results in a long image strip parallel to the flight direction: the transmitted pulse bandwidth is adjusted to always achieve a ground range resolution of 3 m. Spot instrument mode: the radar beam is steered to illuminate a fixed point to increase the illumination time, resulting in an extended Synthetic aperture length, which improves the azimuth resolution. Spot mode uses a 300 MHz pulse bandwidth and provides a slant plane image with a resolution of 0.5 m (range) by 0.25 m (azimuth); when translated into the ground, the products has 1 m resolution covering an area of 5 km x 5 km. Due to multi-looking, speckle noise is significantly reduced As an evolution of Spot mode, SLEA (Spot Extended Area) products are available with the same resolution of Spot data but a scene size of 15 km x 15 km Scan Instrument mode: the phased array antenna is used to create multiple beams in the elevation direction which allows to acquire a large area (100km x 100km) with resolution better than 15m. To achieve the finest image quality of its Scan image, ICEYE employs a TOPSAR technique, which brings major benefits over the quality of the images obtained with conventional SCANSAR imaging. With the 2-dimensional electronic beam steering, TOPSAR ensures the maximum radar power distribution in the scene, providing uniform image quality. Two different processing levels can be requested: Single Look Complex (SLC): Single Look Complex (SLC) Level 1a products consist of focused SAR data geo-referenced using orbit and attitude data from the satellite and the scenes are stored in the satellite's native image acquisition geometry which is the slant-range-by-azimuth imaging plane and with zero-Doppler SAR coordinates. The pixels are spaced equidistant in azimuth and in slant range. The products include a single look in each dimension using the full transmit signal bandwidth and consist of complex magnitude value samples preserving both amplitude and phase information. No radiometric artefacts induced by spatial resampling or geocoding. The product is provided in Hierarchical Data Format (HDF5) plus a xml file with selected metadata. Ground Range Detected (GRD): Ground Range Detected (GRD) Level 1b products consist of focused SAR data that has been detected, multi-looked and projected to ground range using an Earth ellipsoid model. The image coordinates are oriented along the flight direction and along the ground range. Pixel values represent detected magnitude, the phase information is lost. The resulting product has approximately square spatial resolution pixels and square pixel spacing with reduced speckle due to the multi-look processing at the cost of worse spatial resolution. No image rotation to a map coordinate system has been performed and interpolation artefacts are thus avoided. The product is provided in GeoTiff plus a xml file with selected metadata.

In addition, ICEYE has released a public catalogue that contains nearly 18,000 thumbnails under a creative common license of radar images acquired with ICEYE's SAR satellite constellation all around the world from 2019 until October 2020. Access to the catalogue requires registration.
