D on the Earth’s surface with a tilt angle of 52.eight , which permitted for any conical-shaped sweep and permitted coverage of 720 km (878 km just after increase). This antenna rotated about an axis within a nadir position at a speed of 31.6 rpm, but only the front 130 with the circle described by the antenna was utilised to gather the information [70]. Inside the present perform, four parameters originating from this sensor have been evaluated: Ice Water Path (IWP), Rain Water Path (RWP), Convective Precipitation (CP) and Surface Precipitation (SP). PR offers the data for solution 2A25. This sensor was the initial rain radar to be placed in orbit, and its most important objectives have been: (i) to elucidate the three-dimensional structure of precipitation, specifically the vertical distribution; (ii) to obtain quantitative measurements of precipitation more than land and ocean; and (iii) to enhance the general accuracy on the TRMM precipitation measurement by using combined data from active (PR) and passive (TMI and VIRS) sensors [33]. This instrument is definitely an active 13.8 GHz radar, recording energy reflected from atmospheric and surface targets, GNE-371 Biological Activity having an electronic sweep endowed having a bandwidth ofRemote Sens. 2021, 13,six of215 km pre-boost and 247 km post-boost [71]. The sensor produces an estimate of the vertical precipitation price profile for every single radar beam, and this estimate is provided in each of its resolution cells, also applying the radar database installed on the Earth’s surface for comparison purposes [72]. From this sensor, two parameters were utilized: Freezing Level Height (FH) and Reflectivity (dBZ), both extracted from the 2A25 item.Table 1.

Methodological Procedures 2.three.1. Cloud Microphysical Qualities To assess the connection among the occurrence of lightning plus the microphysical qualities of clouds, we used a method similar to that of Chatterjee and Das [18]. The TRMM solution database (2A-CLIM and 2A25) was submitted to a spatiotemporal filter, where the lightning identification data (LIS) had been related to the microphysical data. The orbits in which no lightning was recorded had been selected and a cutout was applied to the study region. Consequently, the pixels on the NEB in which there was no lightning record formed the database named “No Lightning Occurrence”. Then, the orbits in which lightning was identified (in line with the LIS) were submitted to a brand new place filter (latitude and longitude) being captured only information of pixels that coincided with the lightning occurrence (forming the database named “Lightning Occurrence”). For this goal, pixel data were captured within a distance of 0.04 (approximately 4 km) from the centroid of lightning place. This value was selected mainly because it can be related for the resolution from the 2A-CLIM and 2A25 merchandise. Immediately after filtering, two separate databases have been obtained, one together with the microphysics data with the clouds when lightning occurred.
