Research topics

How to manage the uncertainty and variability from renewables and consumption? How to model, optimise and simulate a realistic system? What are the methods to promote green behaviour to support grid flexibility?

Station PAL, Paris region, France

Contribution to BSRN since 2003. Current available parameters in BSRN archive : • SWDn (DIF, DIR,

GLO), LWDn • Air temperature,

RH, pressure The new installation in 2014 will become reference for the site. zone2

How to improve numerical weather predictions?

What are the cloud effects on SWdn and LWdn ?

What are the aerosols effects on solar radiation on pollution peak events ?

How accurate are SWdn and LWdn measurements ?

What is the accuracy of solar resource assessment depending on the data available ?

How radiometers of different quality compare on tilted surfaces?

How to train on SW and LW radiation ?

Questions addressed using the PAL BSRN data


5

Which is the gain of combining photovoltaic panels with reflectors ?


6

Water on the pyrgeometer dome creates a positive measurement offset



7

Bird sitting on the instrument domes creates large spikes in LWDn or large GLO/SUM inconsistencies



8

Situations with broken clouds, with brightness changes on the circumsolar region, might lead to GLO/SUM inconsistencies.

On this day, around 15 UTC, there was a small animal (probably a ladybug) on the window of the pyrheliometer of radflux2.
