<div><br></div><div>Unfortunately after putting three images on one figure, the x-axis labels (2,1.5,1 etc.) and y-axis label (1970, 1975...etc) are too small to read.

<div><br></div><div>Is there are way to make my x and y axis values bigger?</div><div><br></div><div><strong>Question 2: </strong>Please see time series plot. As you can see I have filled values greater than 0 red, and below 0 blue. I would like to only fill values above 0.5 in red and values below -0.5 in blue (corresponding to the phase of the oscillation). I have tried working with the maskout command, but I have been unable to make the entire thing work. </div>

<div><br></div><div><strong>Question 3:</strong><em> </em>I am attempting to plot observation data as well. I am trying to use HADISST or ERSST.v3b. Unfortunately, with the HADISST data, the ncfile s are compressed using GNU zip. I cannot figure out how to move forward and work with this file (it will not allow me to use ncdump until I manipulate the files). Is there a way to handle this type of file?</div>
<div><br></div><div>Alternatively, I am looking at the ERSST files. (See <a href="ftp://ftp.ncdc.noaa.gov/pub/data/cmb/ersst/v3b/netcdf">ftp://ftp.ncdc.noaa.gov/pub/data/cmb/ersst/v3b/netcdf</a>). <em> Is there a way to open ftp site in file explorer and then quickly recursively download and then combine all of the files? </em></div>
<div><br></div><div>Alternatively, ERSST data is available in ASCII, and the files span about 10 years each, and could be more easily combined. However, I don't know the best way to get GrADS to read that data. <em> Is there an external utility that might allow me to convert the ASCII to netcdf? </em></div>
