I have made many new changes to the model2roms toolbox which can create the necessary forcing files for running the Regional Ocean Modeling System (ROMS). All of the details and access to source code is available here through my Github site. Latest version of model2roms is:
I have worked extensively with figuring out how to read GIS Shapefiles using Python lately. I needed to read polygon positions from Shapefiles, extract sea surface temperature data from CMIP5 model ensembles and plot the results. The result is quite neat and i have included the full script required to do re-create the map seen above.
I have just created a small tutorial that explains how use and combine python, numpy, and matplotlib to extract data from openDAP servers. The example retrieves sea surface temperature (SST) data from the new version 4 of the CoRTAD (coral reef temperature anomaly database) satellite archive maintained by NODC-NOAA. The tutorial show how to plot the result and write the results to file. Take alook here if you are interested in really geeky ways to use python. Cheers, Trond
Last week I had the good fortune of going to Juneau in Alaska for a workshop. I had never been to Alaska before and I was really looking forward to visiting the old stomping grounds of gold spectators and other adventurers. Juneau did not disappoint and showed itself from both the rainy, dark foggy side to the light and bright with fantastic views of mountain peaks and glaciers. Although I did not see any bears this time and the salmon run was done for this time of year, I was very pleased with the nautre I could observed in this little town far north in the US, which can only be accessed by plane and boat. I had the opportunity to go for a couple of short hikes with my gracious hosts. Pictures from my trip are found here.
Girona is a city in the northeast of Catalonia, Spain about 30 minutes drive from the coast of Costa Brava.
Girona is an old Roman city that has been through some hard times during the last centuries. The city has been under 25 sieges and has been captured 7 times (Wikipedia). A 7 month besiege by an Napoleonic army in 1809 had catastrophic consequences for the population of Girona. Girona was surrounded by a city wall for centuries, originally built by the Romans, but after the French siege the wall was partly demolished to make room for new development and progress. In recent years, the missing parts of the city walls on the eastern side of the city have been reconstructed. Called the Passeig de la Muralla it now forms a tourist route around the old city. Pictures are found here.
One of my favorite places to visit in the US is San Francisco. I have made a new collection with photos from May 2009, October 2009, and October 2010. I have converted some of the photos into black and white. Check out the collection here.
This weekend Jon and I went for a hike to Fløyen which was covered in clouds. At the top of the mountain, heavy snow started falling and in a short time everything was covered in white. We hiked around Fløyen and then down Knatten which gives an excellent view of Svartediket (drinking water) as well as Ulriken. Along the hike I took some pictures which you can see here.
One of the nicest places to go hiking in Bergen is up Fløyen. Fløyen is one of the seven mountains surrounding Bergen, and it is situated right in town. The mountain is 320 meters above sea-level which is a nice, steep hike that takes you 30-60 minutes depending on your speed and how long you spend taking pictures walking up. You can also take the funicular up the mountain. Once you are at the top (see live web camera here), you can continue hiking the mountain side of Bergen. Liz and I spent the first week of 2011 relaxing in Bergen and we used the opportunity to hike to Fløyen. I have put some pictures from one of our hikes online.
This year Liz and I celebrated Christmas in Skien with the family. It was really cold (-22ºC) with snow and frost characterizing the landscape. We often take a walk that goes through old fields and small forests. With the snow everything looked very photogenic. We went for a couple of those walks and took these pictures.
I recently traveled to Portland, Oregon on the west coast of the US. Portland gave me the feeling of being in a cool, altenative European city. The city has a ton of micro-breweries, nice restuarants, a good music scene, and beautiful scenery. The city also has a fair share of old iron bridges crossing the Willamette River. The pictures I put online are part of my ongoing experimentation with black and white photography. Click here to see them.
