    Foren-Beitrag von Zhang Weiwei im Thema about global radiation(G)

    Dear Dominik,

    I read the instructions. So I've solved the first problem. Mean radiant temperature can be calculated based on global radiation or cloud coverage.

    However, 0 = clear sky to 8 = overcast sky, our cloud cover data usually ranges from 0 to 10. And wind speed is smaller than 0.5 or larger than 17.0 m/s, our wind speed is sometimes below 0.5. How to solve the problem of data scoping?

    Dear Dominik,

    The first question:
    I calculated the daily astronomical radiation (MJ/m ^ 2), 1MJ/d/m ^ 2 =(1000/(3.6*24))w/m ^ 2,
    So, converting the daily astronomical radiation into daily global radiation is correct?

    The second question:
    In addition, I have temperature(℃), wind speed(m/s), relative humidity(%) and cloud cover. Can these data be put into the software to calculate UTCI?

    The last question:
    When vapour pressure is input in the "Current data" box, relative humidity is calculated at the same time.
    However, this result is different from that calculated by a meteorological datafile.
    For example, the vapor pressure is 39.2hPa, relative humidity calculated is 70% in the "Current data" box. But relative humidity calculated is 138.1% by a meteorological datafile and cloud cover is only 0.0. So, could you tell me what's wrong?
    the input file:
    01.06.2019 08:20 23.2 39.2 1.2 367
    the output file:

    Dear dominik_mif ,
    Thank you for your advice. I'm applying for the laster version. Wish me luck.

    Best Regards.

    Dear Dominik_mif ,

    I changed another computer which system was Win7，and I did as you said and it worked. This problem was solved. Thank you for your patient answer.

    I have other questions that I need your help.
    Where can I download the new version?

    The first question:
    '... for all indices, there is meteorological input required for the very location the index is calculated for (in a height of 1.1 m above ground level). The wind speed for UTCI is corrected automatically by the model. ...' This is described in the section 3.2.1.6 on page 11 of the 'RayManManual.pdf'.
    However, we usually have the temperature in a height of 2 meters above the ground and the wind speed in a height of 10 meters above the ground. So do meteorological elements need to be converted into values of 1.1 meters above the ground and then input into the RayMan?

    The second question:
    I don't have radiation data, but I have temperature, humidity, wind speed, cloud cover and other data. I want to confirm that, can these data be directly put into the calculation?

    The third question:
    I just tried the tool and found that one of the UTCI results was '9999'. The input data and results are listed below.
    input data:
    01.06.2019 08:00 23.1 16.2 1.2 322
    01.06.2019 08:10 23.0 16.3 0.8 341

    Dear Dominik_mif ,

    I'm sorry.
    I did it as you told me. However, the same problem applied again.

    The problem: I deleted the currentsession.ini file and retry to open the RayManPro, but the error dialog box appears again, which displayed as 'Exception EReadError in Modul RayMan_20170310. Exe bei 0001 b8cb Fehler beim Lesen von RichEdit1. Lines. The Strings: Fehler bei...'.

    So the RayManPro still doesn't work.

    Looking forward to your reply. Thank you!

    Thank you for your reply.

    The currentsession.ini file does exist in the same folder as the RayManPro.exe.
    But after I deleted it, there is still a same problem. The error picture has been given, please check it.
    I look through the previous rayman1.2 version, there is no currentsession.ini file in the folder.

    Dear developers,

    My computer system has been changed to English version,

    When I open the rayman2017 or RayManPro, the error dialog box appears, and the error display as 'Exception EReadError in Modul RayMan_20170310. Exe bei 0001 b8cb Fehler beim Lesen von RichEdit1. Lines. The Strings: Fehler bei...'.

    But it's normal to use the previous RayMan12 version.

    So why?

    Thank you very much for your help and kind regards.
