Temperature characteristics for few GSOD-Tutiempo stations have been created earlier, for period 1973-2017.

GSOD - Tutiempo observation 1973-2017:
https://meteomodel.pl/forum2/index.php?topic=2328.0

Stations with relative good data and good locations, were choosen, but it can be difficult in warm areas.

Precipitation amount by GSOD, however precipitation data in GSOD are with a lot of fake values and yearly amount of precipitation can be far from real value (like in year 2017). GSOD contains occurrence of rain, snowing, thunder and fog from observation (not from precipitation amount).

Last day of year is missing since 2014 in GSOD data. And at beginning, data are with quite a lot of holes, data are rounded and extreme values can be from observations in termin.

Two stations have been chosen - Praha Libus 11520 and Praha Ruzyne 11518 Night observations (22-06) are at Prague Libus only automatic since September 2012. Observations are once a hour. Praha Ruzyne is main airport, and observations are nonstop with somebody and observations are usually twice a hour. That's why Praha Ruzyne has more days with rain, thunder, fog (one of reasons). But it was before September 2012 similar (there was observations with somebody nonstop at Praha Libus and Praha Ruzyne has in this time more days with rain, snowing, thunder, fog). Observations from Praha Ruzyne are with higher quality, but number of days with rain, thunder, fog depend on position too.

Graphs for significant weather occurrence (rain, snowing, rain or snowing, thunder, fog) are with values 1 (yes) and 0 (no), there is zero space between colums.  Graphs for precipitation amount are with collums, one collum for every day. Space between collums is zero. Lot of big precipitation amount are not true.
