Moshtemp - Steve Mosher: A quick look at GHCN version 4

GHCN version 4 beta is available. Using the GHS population dataset the ~27000 GHCNV4 sites were filtered to collect only rural stations. GHS combines two datasets, a 10meter built surface satellite dataset and a human population dataset. https://ghsl.jrc.ec.europa.eu/. using site locations the population within 10km of the site was extracted. two cases were considered: […]

Moshtemp - Steve Mosher: Modis QC Bits

In the course of working through my MODIS  LST project and reviewing the steps that Imhoff and Zhang took as well has the data preparations other researchers have taken ( Neteler ) the issue of MODIS Quality control bits came up.  Every MODIS  HDF file comes with multiple SDS or multiple layers of data. For

Moshtemp - Steve Mosher: Modis R: Package tutorial

The MODIS package for R For people who work in GIS in R there has been a bit of challenge in working with data from  Modis. I’ll use an example from my own work on UHI to illustrate. A while back I decided that I wanted to look at albedo data from MODIS.  If you

Moshtemp - Steve Mosher: Terrain effects on SUHI estimates

Introduction Zhang and Imhoff (2010)  pdf here utilized NLCD impervious surface area (ISA), Olson biomes, and MODIS Land Surface temperature (LST) to estimate the magnitude of UHI in large cities across the US.  Peng  employed a   similar approach in studying 419 large cities ( population greater than 1m ) around world. Peng’s work suggests a limit or

Moshtemp - Steve Mosher: More Fun With Modis

I’ve started a tutorial on using the MODIS package in R the first few steps are here.  While I wait on a release of the package I thought I would play around a bit with the MRT tool and see how it worked.  Let’s recall where we are going.  I have an inventory of around

Moshtemp - Steve Mosher: City Size and SUHI

In the course of putting together data for my kriging project with the CRN stations, I got another idea related to a small but potentially important corner of the concerns over UHI in the global temperature index. For clarity I suppose I should make it clear that my position is that the UHI bias is

Moshtemp - Steve Mosher: rasterVis to the rescue

Programmers like Oscar Perpiñán Lamigueiro are the reason I love R!  Oscar is the maintainer of the rasterVis package and it in this post I’ll explain why it is must have package for anyone working with the raster package in R.  My latest project is focused on the NOAA’s Climate Reference Network. The details can

Moshtemp - Steve Mosher: 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
