Reanalysis-1 / Reanalysis-2
A global plot of Reanalysis-1 mean relative humidity for the month of January 1948. Notably arid regions of the globe are marked in deep shades of blue. This image was produced by downloading one file of Reanalysis-1 data through NOMADS and visualizing with the Grid Analysis and Display System (GrADS).
A scatter plot of Reanalysis-1 global 1000hPa (near-surface) temperatures versus global 850hPa (about 5000 feet) temperatures for June 1, 1952. Temperatures are in degrees Kelvin. This plot shows the general tendency of temperatures at 5000 feet to follow the trend of air temperatures close to the surface. Generally, the temperatures at the two levels are said to be well correlated. Correlation does not imply causality. This plot was generated by downloading a Reanalysis-1 file through NOMADS and visualizing the data with GNU Octave, an open-source software set similar to Matlab.

A plot of average monthly temperature by latitude and height (decreasing pressure surfaces). Temperatures are in degrees Kelvin (freezing is approximately 273 degrees Kelvin, or 0 degrees Celsius, or 32 degrees Fahrenheit). Northern latitudes are to the right in this diagram. This image was produced by downloading Reanalysis-2 data through NOMADS then visualizing with NASA’s Panoply visualization tool.
