A statistical analysis indicates that summer uptake of CO2 is largely explained (similar to 50% of variance) by air mass exposure to uptake by Siberian and sub-arctic ecosystems. This resulted in an average 5 to 10 ppm difference with overlaying air masses. Stratosphere-troposphere exchange is ...
The protected forest areas generally had more negative AGB changes than the other two land categories and it had on average a loss of −5.79 Mgha-1year-1 with a standard deviation of 13.91 Mgha-1year-1. In contrast, the peak of the density in the other two land categories was around...
2e–f). The pecten, a vascular structure in the eye of birds that is devoid of photoreceptors, created a blind spot in the visual field that had a vertical length of 60°, with an average width of 14.0 ± 0.7° (Fig. 2e). We found that meadowlarks moved their eyes an average of ...
Over the past week, the greater Seoul area reported 293.1 new infections on average each day, while the non-greater Seoul area reported 153.6 daily new infections, Yoon said. Yoon expressed concerns about a rise of coronavirus infections in non-greater Seoul areas. The KDCA said it is closely...
In addition to measuring the column average CO 2 mixing ratio from the laser signals reflected by the ground, the CO 2 Sounder lidar also recorded the height-resolved attenuated atmospheric backscatter profiles beneath the aircraft. We have recently processed these vertical p...
Nevertheless, TS-X still shows an underestimation, while RS-2 is overestimating canopy height in average. Table 3. Validation statistics of canopy heights per interferogram based on LiDAR data. (𝐶𝐻 CH¯Ref = mean of the reference canopy height, 𝐶𝐻 CH¯Est = mean of the ...
