My Interest in GLORY: Total Solar Radiation Claus Frã¶hlich Physikalisch-Meteorlogisches Observatorium Davos, World Radiation Center, CH 7260 Davos Dorf, Switzerland eMail: cfrohlich@pmodwrc.ch ; http://www.pmodwrc.ch Solar Radiometry: outright exactness, strength Understanding variability of sunlight based irradiance GLORY Science Meeting 17-18 January 2006

Slide 2

How Accurate are Space Radiometers Until the dispatch of SORCE and the operation of TIM we all felt that we have enhanced the vulnerability from the early time of HF and ACRIM I. The composite shows how little the variety is contrasted with the information\'s spread. It indicates additionally that the exactness is much higher than the total precision which permits to build such composite with covering estimations. Greatness Science Meeting 17-18 January 2006

Uncertainty of PMO6V WRR/SI GLORY Science Meeting 17-18 January 2006

Slide 4

Final estimations of VIRGO TSI toward the Mission\'s Beginning DIARAD is completely portrayed and speaks to its own autonomous radiometric scale. In any case, a few amendments because of time steady impacts and the range have been resolved subsequent to the first assessment; they add up to a general rectification of + 447 ppm. With these revisions the last ‘first light’ information of VIRGO are exceptionally predictable (inside around 300 pmm), in spite of the fact that their following to SI is totally autonomous. Grandness Science Meeting 17-18 January 2006

Slide 5

VIRGO Measurements: What do we learn? Level-1 are adjusted for every known impact (electrical alignment, temperature, S/C position, and so on) Level-1.8 needs to remedy for debasement, early increment and so forth by sun oriented presentation. Presentation ward changes can be redressed by examination with a less uncovered radiometer of the same sort. Level-2 is the last item, which incorporates the two\'s examination diverse sorts on VIRGO. This has uncovered non-introduction changes of DIARAD, which can\'t be resolved without correlation to PMO6V. Radiance Science Meeting 17-18 January 2006

Slide 6

Comparison to TIM/SORCE VIRGO Measurements: Results Level-2 of VIRGO is an outcomes\' mix of PMO6V and DIARAD level-1.8, the recent being rectified for non-introduction subordinate affectability changes. By examination with 1-year separated ACRIM and all the more as of late TIM information, the adjustments\' offer for each is resolved. Grandness Science Meeting 17-18 January 2006

Comparison of revised TSI on occasion of ERBS GLORY Science Meeting 17-18 January 2006

Slide 8

Conclusions for Solar Radiometry from Space The contrasts between established radiometers and TIM are still not determined and the reason is obscure. It doesn\'t appear to be because of gap regions, as it was in all likelihood amid the early estimations of TSI from space. The great understanding in the middle of PMO6V and DIARAD-L which have totally diverse approaches to follow to SI, demonstrates that the VIRGO results are most likely near the SI (inside around 300 ppm). There may even now be an issue with the WRR/SI correlation: the WRR element of PMO6-9 and 11 are of the request of 1.004258 and 1.002751, showing that the described PMO6 radiometers speak the truth 0.35% beneath the WRR. The achievement of the WRR/SI correlation at NPL gives the premise to comparative examination with TIM and ACRIMs at NIST sooner rather than later. Brilliance Science Meeting 17-18 January 2006

Slide 9

Total Solar Irradiance Variability keeping in mind the end goal to get a solid time arrangement we require a composite. One can simply trust them and consolidation them. Be that as it may, there are a few known issues which require rectifications. We rapidly experience and show how the PMOD composite is built Comparison of the three composites GLORY Science Meeting 17-18 January 2006

Slide 10

Comparison with Proxy Models We can manufacture an intermediary model considering the sunspot, faculae and system. The sunspots by PSI, the faculae by MgII st and the system by MgII lt . Cycle 23 demonstrates a few issues with the long haul – possibly instrumental or some impact of spots on MgII. Magnificence Science Meeting 17-18 January 2006

Slide 11

Conclusions for TSI Variability The reproductions utilizing magnetograms are exceptionally effective, showing that the sun powered turn and the 11-year-cycle varieties are because of the attractive fields identified with movement. The intermediary models demonstrate, that the 11-year cycle is because of the system and not straightforwardly identified with dynamic area spots and faculae. It appears to be hard to associate TSI with action records as SSN. Eminence Science Meeting 17-18 January 2006
