Selected Analyses

The following are selected analyses that may or may not have made it into the report. Oftentimes the figure number is not the same as in the report.



Figure xx (MSU D, C, and D minus C). Produced on Thursday 9 December.

MSU D is in red, C in orange, and D minus C is in gray.
The PostScript file for this figure is linked here.


Possible cover ?

In each row the left panel is UKMO surface temperature trends and the right panel is MSU 2lt temperature trend. This is Figure 6.2 shown in a satellite projection. The top row is centered at 30N,110W and should be used on the front cover. The bottom row is centered at 30S,70E.

Figure "minmax"

The minimum and maximum temperatures are drawn as black and light gray lines, respectively. The difference, maximum minus minimum, is drawn below as a slightly darker gray line.

Rich Muller: ASCII file for the seasonal time series and a PostScript file for the figure.

Figure 2.2.

December-January-February mean MSU 2LT for the indicated years. Shading interval 1C, and the equator is drawn as a gray line.

Figure "radiosonde locations." Map of radiosonde locations.
"GOS" ---- there are 905 stations in this file.

There is a radiosonde at the South Pole.

Figure 2.3

Same as Figure 2.4, but for global-averages. The ordinate tick interval is 0.25C.

Rich Muller:
  • ASCII file with data: MSU, radiosonde, and surface temperatures are the order of the columns.
  • The PostScript file of the plotted data is here. Ignore the Figure 3.1 annotation.

    
    
    Figure 2.4

    Tropical seasonal-mean MSU 2LT (red), radiosonde (green), and Jones surface temperature (black) in deg. C. The first season is March-April-May 1979 and the last season is December1998-January1999-February1999.

    Figure 2.5

    Global seasonal-mean surface temperature (Jones) in deg. C. The first season is March-April-May 1979 and the last season is December1998-January1999-February1999. The y-intercept and trend (deg.C/yr) are 0.0029 and 0.0189, respectively.

    Figure 6.1

    Fig. 6.2

    1979-98 surface (top) and MSU 2lt (bottom) trends, respectively. The surface trends have been smoothed once along latitude circles with a 3-point running mean. This smoother also has the effect of interpolating isolated and adjacent pairs of grid boxes for which no trend was calculated. The filled grid boxes occur over parts of South America, Africa, and at high latitudes. The remaining grid boxes for which no trends were calculated are shaded gray (high latitudes of each hemisphere).

    Figure 7.2

    Reynolds SST (black), MSU C + orbital decay (aqua), and MSU D (red). The values of both MSU series have been divided by 1.6, consistent with Wentz and Schabel (1999).

    Figure 7.3a

    NCDC (purple), UKMO (black), GISS (aqua). The NCDC and GISS best-fit straight line are essentially the same.

    Figure 7.4

    Location of surface temperature observations. The map is a composite of all of the Global Historical Climatology Network mean temperature stations (large dots) and the ship-based observations from a single week used in the production of the Reynolds and Smith (1994) sea surface temperature dataset (small dots).

    Figure 9.1

    Global-averages of MSU 2LT at all-gridpoints (red) and only at radiosonde grid boxes ("subsampled") (light red). "Subsampled" minus all-gridpoints is plotted below.

    Figure 9.2.

    Global-averages of MSU 2LT at radiosonde grid boxes (light red) and radiosonde measurements themselves (green). MSU minus radiosonde plotted at the bottom.
