Step S101 is simulating the concentration of atmospheric CO, according to the assimilation meteorological observation data obtained by the Goddard earth observation system based on the GEOS-Chem model to obtain atmospheric XCO: space-time continuous distribution simulation data.
In the embodiment of the present application, large-scale (long time series) meteorological element (atmospheric CO: concentration) data is simulated by the atmospheric chemical transmission model GEOS-Chem according the assimilation meteorological observation data obtained by the Goddard earth observation system, and XCO: space-time continuous distribution data (planar data) required for observation time is obtained to reflect a spatial distribution trend of the atmospheric XCO: (as shown in Fig. 3).

Wherein, the pressure weight function of atmospheric COzconcentration is calculated according to the formula (1), and the formula (1) is as follows:
/ | Ë % he = [otitis … (1) \ n= / \ n= J Bsurs in the formula, h represents the pressure weight function of atmospheric CO: concentration, 1 represents the number of layers for layering the atmosphere according to the equal air pressure surface, and 1 is a positive integer; psurr represents the surface pressure; pi, Pii represent pressures at the upper and lower boundaries of the i-th layer, respectively.
In the embodiments of the present application, according to the isobaric surface, the atmosphere is divided into n lavers i€{l, 2, 3...n), where i and n are both positive integers.
Wherein, the pressure weight function of atmospheric CO; concentration for the first layer of the atmosphere is: 3 Ba 2 1 BTR In 22 ours Pi The pressure weight function of atmospheric CO: concentration for the n-th layer of the atmosphere is:

In the embodiments of the present application, the preset step length is 6 hours, namely based on the GEO5-Chem model, according to the assimilation meteorological observation data obtained by the Goddard earth observation system, the concentration of atmospheric CO: is simulated by taking hours as a unit, and a simulation result is output every 6 hours on average. Wherein, the smaller the preset step length is, the higher the output accuracy of the simulation result is.
Step S102 is fusing XCO: observation data obtained by the TanSat satellite observation and atmosphere XCO: space-time continuous distribution simulation data based on the HASM method to obtain space-time continuous distribution XCO: fusion data. In the embodiments of the present application, although the large-scale observation can be realized by observing the space-time distribution of XCO; through satellites, due to the limitations of satellite operating orbits and data resolution, there are many vacancies between the observation data of each orbit, and the types of satellite observation data are in the spatial data vector format belongs to "point data”, that is, the XCO: observation data obtained by the TanSat satellite is point data (as shown in Fig.4), although it can represent the local details of atmospheric XCO:, it cannot obtain continuous spatial distribution information.

Therefore, the XC0, fusion data with space-time continuous distribution has higher data accuracy and higher resolution, which lays a foundation for the study of carbon flux.
In the embodiments of the present application, particularly, based on the HASM method, fusing the mean value of the XCO; observation data of the TanSat satellite in the same grid with the atmospheric XCO; space-time continuous distribution simulation data after the atmospheric grid division is performed, so as to obtain space-time continuous distribution XCO: fusion data; wherein the atmosphere is divided with a spatial resolution of 0.1° x0.1°.

0.1°x0.1°, and there may be multiple observations in the same grid, the mean value of the multiple observations is extracted as the optimal control condition of the corresponding grid, and is fused with atmospheric XCO: space-time continuous distribution simulation data in the corresponding grid.
In some alternative embodiments, the HASM-based XCO: data fusion method further comprises: verifying the space-time continuous distribution XCO: fusion data according to the atmosphere XCO: ground observation data obtained by observation of the ground TCCON observation station.

Specifically, by comparing the grid value of XCO: extracted from the corresponding ground TCCON observation station in the space-time continuous distribution XCO: fusion data with the ground observation data of atmospheric XCO:, the error in the XCO: fusion data with space-time continuous distribution is analyzed to verify the space-time continuous distribution XCO: fusion data (as shown in Fig.6).
For example, the minimum error (MIN), the maximum error (MAX), the mean error (ME), the absolute mean error (MAE) and the standard error (ESD) of the ground TCCON observation station within a predetermined time are counted. Specifically, under the same space-time matching rule, the atmospheric XCO: ground observation data of the ground TCCON observation station are matched with the XCO; observation data of the TanSat satellite, the GOSAT satellite and the OCO-2 satellite in a synchronous space-time manner, and the atmospheric XCO: ground observation data of the ground TCCON observation station are compared with the mean values of the atmospheric XCO: ground observation data of the TanSat satellite, the GOSAT satellite and the OCO-2 satellite under the same space-time respectively, so as to obtain the error results of the atmospheric XCO 2 ground observation data of the TanSat satellite, the GOSAT satellite and the OCO-2 satellite and the atmospheric XCO: ground observation data of the ground TCCON observation station under the same space-time, to extract the maximum error, the minimum error, the mean error, the absolute mean error and the standard error.
In the embodiments of the present application, under the space-time matching rules of + 2h and + 1 °, the same space-time matching is performed on the atmospheric XCO: ground observation data of the ground TCCON observation station and the XCO: observation data of the TanSat satellite, the GOSAT satellite and the OCO-2 satellite, respectively.
Table 1 shows the error statistics of the atmospheric XCO: space-time continuous distribution simulation data and the atmospheric XCO: ground observation data obtained based on the GEOS-Chem model, and error statistics of the obtained XCO: fusion data with space-time continuous distribution and atmospheric XCO: ground observation data after the atmospheric XCO: space-time continuous distribution simulation data being fused with the XCO: observation data obtained by the TanSat satellite observation. As shown in Table 1, the error statistics of the space-time continuous distribution XCO: fusion data and the atmospheric XCO; ground observation data are greatly improved compared with the error statistics of the driving field GEOS-Chem and the TCCON observation station. For example, the ME and MAE of the driving field are 1.51 ppm and
2.45 ppm, respectively. the ME and MAE after TanSat fusion are reduced to 0.64 ppm and 1.62 ppm, respectively, in the XCO: fusion data of space-time continuous distribution , MAE can better reflect the error change, and the accuracy after fusion is improvedby 0.83 ppm.
In terms of standard deviation of error, the mean value of ESD after fusion is 1.9 ppm, which is 0.7 ppm lower than that of driving field of 2. 6ppm.
