Abstract

This paper presents an improved photon path length probability density function method that permits simultaneous retrievals of column-average greenhouse gas mole fractions and light path modifications through the atmosphere when processing high-resolution radiance spectra acquired from space. We primarily describe the methodology and retrieval setup and then apply them to the processing of spectra measured by the Greenhouse gases Observing SATellite (GOSAT). We have demonstrated substantial improvements of the data processing with simultaneous carbon dioxide and light path retrievals and reasonable agreement of the satellite-based retrievals against ground-based Fourier transform spectrometer measurements provided by the Total Carbon Column Observing Network (TCCON).

Fig. 1.

Simplified flow chart showing the basic steps for the PPDF-S GOSAT data processing. Two overlapping layers from the surface to the variable retrieved altitudes (layers 1 and 2) allow for light path modification. The optical path within layer 3 (from the upper boundary of layer 2 to the top of the atmosphere) is not modified [14]. PPDF parameters for Rayleigh light scattering are pre-estimated in the oxygen A-band (0.76 μm) for layer 2. Aerosol/cloud PPDF parameters are retrieved simultaneously with gas amounts from all three GOSAT TANSO-FTS short-wavelength infrared (SWIR) bands for layer 1. The retrievals use a three-layer PPDF model [14] to account for light path modifications and up to 22 atmospheric layers to account for vertical distribution of gas absorption (meteorological parameters and gas profiles). Temperature and pressure grid point values were provided by Japan Meteorological Agency (JMA).

GOSAT sampling domain (15°latitude×45°longitude grid box, yellow rectangle) around Izaña TCCON site (yellow star). Red symbols indicate the location of GOSAT single soundings available for data processing from June 2009 to July 2010. 92% of GOSAT soundings over land (northern Africa) were derived under GOSAT gain M mode, indicating bright Saharan desert surfaces. Only sun glint areas were available to measure over the ocean due to the sufficient reflected signals, so strips are seen in the map.

Time series that correspond to GOSAT single scan XCO2 (gray crosses), GOSAT weekly mean XCO2 data (open blue symbols with bars representing standard deviation), single scan ground-based FTS measurement (solid red symbols), and daily mean XCO2 atmospheric model (green and dark yellow symbols) over the Izaña site. GOSAT data were collected within a 15°latitude×45°longitude grid box centered at Izaña (Fig. 3) and presented separately for observations over land (western Africa, left-hand panel) and sea (North Atlantic Ocean, right-hand panel). Top to bottom panels correspond to different GOSAT XCO2 retrieval algorithms (indicated in the legends of the panels). Green and dark yellow symbols correspond to modeled XCO2 at 20° and +20° longitude shift from Izaña site, respectively. NS indicates the number of GOSAT soundings accessible to be processed.

Time series of PPDF parameters α (top panels) and ρ(middle panels) retrieved with PPDF-S algorithm from single GOSAT scans (gray crosses) and weekly mean PPDF data (open circles with bars representing standard deviation). GOSAT data were collected within 15°latitude×45°longitude grid box centered at Izaña site (Fig. 3) and presented separately for observations over land (western Africa, left-hand panel) and over sea (North Atlantic Ocean, right-hand panel). Green lines indicate the threshold of PPDF parameters beyond which the retrievals were rejected according to postprocessing filter (Section 2.B). Histograms in the bottom panels represent seasonal variability in the total AOD (averaged over 15 days at 1.6 μm) from a global three-dimensional aerosol transport-radiation model.

Correlation diagrams between GOSAT and ground-based TCCON measurements of XCO2 for two GOSAT retrieval algorithms, PPDF-S (bottom panels) and NIES L2 02.xx (top panels), and for three sets of TCCON sites, over Lamont (left-hand panels), over the other seven Northern Hemisphere sites (middle panels), and over three Southern Hemisphere sites (right-hand panels). The GOSAT single scans were selected during 14 months from June 2009 within a 5° radius latitude/longitude circle centered over each TCCON station. The analyzed ground-based FTS data were mean values measured within ±1h of the GOSAT overpass time. Red lines correspond to the best fits, and the green line represents one-to-one correspondence. The number of coincident soundings and characteristics of statistical relationships between ground-based FTS and GOSAT XCO2 for each set of TCCON stations is listed in the legend of each panel.
