In November 2015, a new Solar Irradiance Climate Data Record (CDR) consisting of total and spectral solar irradiance and their associated time- and wavelength-dependent uncertainties was presented to the public. The 400+ year climate data record extends from 1610 […](Read more»)
We are releasing a new data product for SOLSTICE. Instead of binning the daily spectrum to 1-nm intervals, users can now download the full-resolution spectrum for each day. The individual spectral scans are combined and a mean spectrum for the day is fit with a spline. The instrument has a spectral resolution of 0.1-nm, and each scan takes samples every 0.03-nm, i.e. three samples per slit width. Doppler shifts due to spacecraft motion slightly offset these scans, thus improving the statistical sampling. The new data product evaluates the spline fit every 0.03-nm, revealing details of the solar spectrum that had previously been obscured by binning. At the time the SORCE mission was proposed, it was assumed that 1-nm intervals were sufficient for state of the art climate models. Today’s models are more advanced, and may be able to take advantage of the full SOLSTICE resolution. The following figure shows a portion of the solar spectrum including the Magnesium II cores and the spectral variability over one rotation(Read more»)
Each summer, the SORCE mission funds student research projects as part of the University of Colorado’s Research Experience for Undergraduates (REU) program. For ten weeks, the students come to Boulder, Colorado to work with SORCE scientists on a research project involving measurements from SORCE. They begin their time at LASP with a one-week lecture series […](Read more»)
The last few months have been challenging for the SORCE Mission Operations team as they work to bring SORCE science measurements back to life. Their hard work has paid off and in recognition for everything they have done, from creative problem solving to extraordinary long hours, Tom Woods (SORCE Principal Investigator) and Bill Possel (LASP […](Read more»)
