Hurricane Irma, as seen by the wet zenith delay (annimation)

I was approached via e-mail by a Canadian journalist to provide information about Hurricane Irma. I asked my PhD student Thalia Nikolaidou to build an animation showing the progress of the hurricane as seen from the wet portion of the zenith neutral-atmospheric delay that affect GNSS observations. To build the animation, Thalia computed the zenith wet delay (ZWD) from the grid of NOAA's numerical weather prediction model NCEP1.  We can see the progress of the hurricane as the white inside the yellow, the colour that represents the highest values of ZWD. Date is indicated at the upper portion of the animation.

Fui abordado por e-mail por um jornalista canadense para fornecer informações sobre o furacão Irma. Pedi à minha aluna de doutorado Thalia Nikolaidou que fizesse uma animação mostrando o progresso do furacão, visto da parte úmida do atraso zenital na atmosfera neutra que afeta as observações do GNSS. Para criar a animação, Thalia calculou o atraso zenital úmido (ZWD) a partir da grade do modelo de previsão numérica do tempo NCEP1 da NOAA. Podemos ver o progresso do furacão como o branco dentro do amarelo, a cor que representa os valores mais altos de ZWD. A data é indicada na parte superior da animação.

Churchill, feeling settled and confortable after the long trip

Image
Our pet Churchill is just 6 months old and we were concerned about how he would react after the long trip. He seems to have adapted well as he is the same lively and playful dog. He likes to play all the time, enjoys long walks in a park close by, goes up and down stairs in no time (in spite his small size) and likes to be present. When he wants peace, he goes to his chosen "secret hideout" underneath the bed. Nosso cãozinho Churchill tem apenas 6 meses de idade e nós estávamos preocupados sobre como ele reagiria após a longa viagem. Mas ele demonstra ser o mesmo cão alegre e brincalhão. Ele gosta de jogar o tempo todo, gosta das longas caminhadas em um parque por perto, sobe e desce escadas rapidamente (e apesar de seu tamanho pequeno) e gosta de estar presente em tudo. Quando ele quer a paz, ele vai para o seu "esconderijo secreto" por baixo da cama. Churchill inspecting my work Churchil inspecionando meu trabalho  Happy after a long

Geodetic Observatory Pecný and the village of Ondřejov

Image
We spent two weeks at the Geodetic Observatory (GO) Pecný, located in a hill 1.5 km near the village of Ondřejov. Ondřejov itself is about 1 hour by public transportation from Prague. A bucolic and picturesque place, located inside a forest. We stayed in a small cottage they have for visiting researchers and scholars. GO Pecný date back to the 1960's and their main activity was the determination of astronomical latitude, longitude and azimuth, evening operations. Later on, they started to perform satellite photography, also evening operations. Therefore, an infrastructure was necessary for the scientists and technicians to stay overnight. The main office building, built at that time, had offices each one with a bed, and every floor had a kitchen, bathroom and shower. Today, a similar way of working exists. The scientists, engineers and technicians may spend two or three days living in the office, doing the rest of the work in other places such as Prague, Plze ň ,  or even at t
