BerkeleyEarth Version 1.6
Version 1.6 has just been submitted to CRAN and I will post the source here in the dropbox. Version 1.6 will probably be stable for a long time unless I find a bug. The main additions I made were adding a few functions to make some things easier, and I converted two files–flags and sources– to file.backed.big.matrixes. Thus the read() routi...

Anthromes and UHI
With BerkeleyEarth 1.6 posted to CRAN I figured it was time to do some sample programs to explain how the package worked and integrated with other packages. Also, I have some issues to check out with the metadata; and in the long run I want to reformulate my metadata package to include some new resources. There is a great project I found at http...

More Anthromes !
First off let me thank folks for all the comments and suggestions. I’m just starting to explore this data so perhaps I should explain how I go about doing this. First off, I am looking for a global bias in the record from UHI. It is well known that you can look through the data and stations and find “cases” where an urban station looks to...

Cooling Stations
Over the course of the past few years I have taking a look at cooling stations a few times but never in much depth. A few other people have looked at them, but usually without much rigor. The standard approach is to find some cooling stations and then conclude that somehow global warming is thereby challenged as a theory. I supp that argument wil...

Metadata Dubuque and UHI
I’m in the process of remaking all the metadata from scratch and looking once again at the question of UHI. There are not any global conclusions we can draw from the data yet; I’m just in the process of checking out everything that is available that could be used to illuminate the problem. The problem, as I see it, is as follows. We know from...

Using bigmemory for a distance matrix
The process of working on metadata and temperature series gives rise to several situations where I need to calculate the distance from every station to every other station. With a small number of stations this can be done easily on the fly with the result stored in a matrix. The matrix has rows and columns equal to the number of stations and it i...

Nick Stokes Distance code, now with Big Memory
In my last post I was struggling with getting a big memory version of the distance matrix to work fast. Nick and other readers had some suggestions and after puttering around with Nicks code I’ve adapted it to big memory and not impacted the run time very much. For comparison writing a 10K by 10K matrix was taking minutes and I projected ab...

Updates to Old code
I notice from time to time that people download code from the drop box. The drop box lags CRAN. I’ve upload the newest versions to the drop box. In the future I will post new releases to the drop box before I submit to CRAN. Related To leave a comment for the author, please follow the link and comment on their blog: Steven Mosher's Blog....

A gWidgets GUI for climate data
If you haven’t worked with the gWidgets package it’s worth some time exploring it which is what I’ve been doing for a little paleo project I’ve been working on. After struggling with the few demos and tutorials I could find I went ahead and bought the book: Programming Graphical User Interfaces in R. Luckily the book was a little better t...
