Surface Stations

People have quite reasonably asked about my connection with the surface stations article, given my puzzlement at Anthony’s announcement last week. Anthony described my last-minute involvement here. As readers are probably aware, I haven’t taken much issue with temperature data other than pressing the field to be more transparent. The satellite data seems quite convincing […]

NASA GISS – Adjusting the Adjustments

As a simple exercise, I quickly revisited the everchanging Hansen adjustments, a topic commented on acidly by E.M. Smith (Chiefio) in many posts – also see his interesting comments in the thread at a guest post at Anthony‘s, a post which revisited the race between 1934 and 1998 – an issue first raised at Climate […]

The Talking Points Memo

The NOAA Talking Points memo falls well short of a “full, true and plain disclosure” standard – aside from the failure to appropriately credit Watts (2009). They presented the following graphic that purported to show that NOAA’s negligent administration of the USHCN station network did not “matter”, describing the stations as follows: Two national time […]

NOAA versus NASA: US Data

Anthony has a post reporting NOAA’s 2008 results, with NOAA reporting: For 2008, the average temperature of 53.0 degrees F was 0.2 degree above the 20th Century average. Anthony showed the following image from NOAA: Readers need to keep in mind that there is a substantial “divergence” between NOAA US and NASA US temperatures as […]

Gridding from CRN1-2

In order to assess the 2006 anomaly in John V’s 2006 calculation reported previously, I’ve calculated a gridded anomaly for the U.S. using standard spatial smoothing software in R. This enables the calculation to be done in a few lines as explained below. I’ll also show results which reconcile most of the results to date. […]

A Second Look at USHCN Classification

Yesterday, I posted up a first look at differences between station histories classified as CRN=1 (good) versus CRN=5 (bad) – a simple comparison of averages, noting that other factors may well enter into the comparison. A couple of other points that I’ve made consistently as we look at these results which I’d like people to […]
