Hello, I am trying to use pcolor to plot some brightness temperature data. My main concern is this graphic bug that produces a large blotch on the graph (see below). Is there any way to get rid of this? Also a second question, how can I get the colors to "pop" more, for instance, in the graph the entire swath of data looks to be about zero but it just seems that the colors are not being represented colrrectly with the colorbar.
c = load('coast');
hold on;
u = load('us_state_map.mat');
netc = 'AMSR2-PRECIP_v2r0_GW1_s201807150047020_e201807150226000_c201807150249550.nc';
ncdisp(netc);
lat=ncread(netc,'Latitude_for_High_Resolution');
lon=ncread(netc,'Longitude_for_High_Resolution');
rr=ncread(netc,'Rain_Rate');
pcolor(lon,lat,rr)
plot(c.long,c.lat,'b')
plot(u.state_lon,u.state_lat)
