Figure 1 shows the allaround tropospheric wet delay at the angles of ten and 60in Qingdao on 25 June 2017 (DOY 206). The geomagnetic con four of 11 quiet on this certain day. The strong line in the figure refers to the calculated by Marcor technology (hereafter referred to as the Marcor te Figure 1 the dotted line refers wet delay in the angles of elevation of 5 , delay value); shows the allaround troposphericto the model worth calculated by , and 60 in Qingdao on 25 June 2017 (DOY 206).

Tropospheric wet delay at various angles of elevation.Figure 1. Tropospheric wet delay at various angles of elevation.As observed, the projection function is accurate with regards to a high angle of elevation (60 ). The wet delay calculated by the two techniques above features a good consistency. Therefore, As observed, the projection function is correct regarding a high an the wet delay calculated by means of Marcor technologies is also precise. Because the angle from the wet delay wet delay Bopindolol MedChemExpress increases rapidly, as well as the difference between has (60. elevation decreases, thecalculated by the two strategies above them a goo also increases At diverse Marcor technology wetdelay Consequently, the rapidly. the projectionazimuthby means of Marcor technologies is al wet delay calculated angles, the values. The nonuniformity of values are higher than function wetdelay the the troposphere within a horizontal direction isthe wet the calculation of your projection and angle of elevation decreases, ignored in delay increases quickly, function wetdelay worth. The differences in tropospheric wet delay at diverse azimuth in between them also increases rapidly. At different azimuth angles, the Ma angles can’t be reflected. The Marcor technology wetdelay worth can totally reflect the environmental qualities about the test web-site. A sea zone is observed inside the range of 90 70 , as shown in Figure 2 (the red star represents the test web-site). The wet delay is reasonably significant. The wetdelay value at an angle of elevation of 5 is 0.six m bigger than the projection function wetdelay worth. Inside the northern region, the deviation between them is somewhat modest.Atmosphere 2021, 12,reflect the environmental traits about the test web site.
