Last week I released version 1.9.0 of Py6S – my Python interface to the 6S radiative transfer model. It’s been the first non-bugfix release for quite a while (mainly because I’ve been busy with paid work), and so I just wanted to highlight a few aspects of the release. The full release notes are available […]
A user of Py6S recently contacted me to ask if it was possible to get an output of Rayleigh reflectance from Py6S. Unfortunately this email wasn’t sent to the Py6s Google Group, so I thought I’d write a blog post explaining how to do this, and showing a few outputs (reminder: please post Py6S questions […]
I’ve been doing a bit of freelancing ‘on the side’ for a while – but now I’ve made it official: I am available for freelance work. Please look at my new website or contact me if you’re interested in what I can do for you, or carry on reading for more details. Since I stopped […]
Just a quick reminder that you’ve only got until next Tuesday to bid for a day’s work from me – so get bidding here. The full details and rules are available in my previous post, but basically I’ll do a day’s work for the highest bidder in this auction – working on coding, data science, […]
Summary: I will do a day’s work for the highest bidder in this auction. This could mean you get a day’s work from me very cheaply. Please read all of this post carefully, and then submit your bid here before 5th Feb. This experiment is based very heavily on David MacIver’s experiment in auctioning off […]
A while back a friend on Twitter pointed me towards a question on the GIS StackExchange site about the 6S model, asking if “that was the thing you wrote”. I didn’t write the 6S model (Eric Vermote and colleagues did that), but I did write a fairly well-used Python interface to the 6S model, so […]
I’ve posted before about the cloud frequency map that I created using Google Earth Engine. This post is just a quick update to mention a couple of changes. Firstly, I’ve produced some nice pretty maps of the data from 2017 over Europe and the UK respectively. I posted the Europe one to the DataIsBeautiful subreddit […]
There was a question recently on the Py6S mailing list about what data sources are best to use to provide atmospheric parameters (such as AOT, water vapour and ozone) for use with 6S, other atmospheric Radiative Transfer Models (such as MODTRAN) or other atmospheric correction algorithms (such as ATCOR). In the spirit of ‘reply to […]
As part of my fellowship with the Software Sustainability Institute, I’ve written an article on Software Sustainability in Remote Sensing. This article was originally written a couple of years ago and it never quite got around to being published. However, I have recently updated it, and it’s now been posted on the SSI’s blog. I’ve […]
I was going to post this as one of my ‘previously unpublicised code’ posts, but that would be stretching the title a bit, as I have previously blogged about my implementation of the van Heuklon (1979) ozone model. This is just a brief update (in the spirit of my ‘previously unpublicised code’ posts) to say that […]
