Publishing this post now in advance of completion to have it available in another post. More details of the companion KML file to be added. I started this blog in 2010, discussing shortcomings in the station location metadata used in … Continue reading
Post to be completed when the post Self-adjusting the Adjustments is complete. Posted now as placeholder to allow linkage from previous post. Location metadata Temperature data
Further content coming soon. This placeholder post published now to allow a link to the coming post to be included in an online comment. Hansen et al. 1999 (Hansen, J., R. Ruedy, J. Glascoe, and M. Sato, 1999: GISS analysis … Continue reading
As completion of this post was long delayed, I’m posting the discussion part separately here as an ‘aside’ post so that it will show up as a new post for anyone who has given up waiting. The most striking aspect … Continue reading
GHCN monthly data (v2 or v3) may not always be quite what it seems. Consider Nitchequon (Canada: 40371826000), looking here at the five individual time series in GHCN v2: Some missing years – but where’s the problem?
The initial GISTEMP steps are described in gistemp.txt in the new GISTEMP (v3) source:
Just over two years ago, when notifying NASA Goddard (GISTEMP) of errors in station coordinates in their v2.inv file, derived from the corresponding GHCN file, I also contacted Russell Vose at NOAA directly, rather than assuming he would be contacted … Continue reading
The quality of GHCN metadata, in particular the latitude and longitude coordinates of stations, remains unsatisfactory. In fact the transition from v2 to v3 might suggest that renaming might be in order – judging by the nature of the metadata … Continue reading
The draft journal article “Current GISS Global Surface Temperature Analysis” posted at http://data.giss.nasa.gov/gistemp/paper/gistemp2010_draft0319.pdf provides a link to the nightlight radiance data set [Imhoff et al., 1997] used [http://www.ngdc.noaa.gov/dmsp/download_rad_cal_96-97.html] (measurements made between March 1996 and February 1997)] at a resolution of 30″ x 30″.
While I was unable to simultaneously view the terrain detail and the NASA nightlight layer which comes with Google Earth, the nightlight radiance data from the TIFF files in this data set can be added to the Google Earth tours described in my earlier post. Continue reading
