There is aviable archive with aerological soundings since 1973 through whole world on the web server of University of Wyoming http://weather.uwyo.edu/ . Values from sounding are usually for 15 standard pressure levels and some specific levels. There are a lot of indexes from aerological soundings.

Standard pressure levels are: 925 hPa 850 hPa 700 hPa 500 hPa 400 hPa 300 hPa 250 hPa 200 hPa 150 hPa 100 hPa 70 hPa 50 hPa 30 hPa 20 hPa 10 hPa. Here in this project - all soundings are always from Czech station Praha Libus 11520.

Level 850 hPa is often discussed. The 850 hPa temperature marks, how warm is current air mass. Three standard levels 850 hPa 700 hPa 500 hPa are very often discussed, like standard levels in lower troposphere.

There are TXT files aviable from every sounding at Archive of University of Wyoming. Most of dermins are aviable. Not only temperature, but 10 different characteristic are for every level. And there are lot of indexes computed from whole sounding.

10 characteristics per every level

HGHT Geopotential Height - meter
TEMP Temperature - celsius
DWPT Dewpoint Temperature - celsius
RELH Relative Humidity - percent 0-100
MIXR Mixing Ratio - gram per kilogram
DRCT Wind Direction - degrees true 0-355
SKNT Wind Speed - knot
THTA Potential Temperature - celsius, original kelvin value 273.1 higher
THTE Equivalent Potential Temperature celsius, original kelvin value 273.1 higher
THTV Virtual Potential Temperature celsius, original kelvin value 273.1 higher

Description of indexes
http://weather.uwyo.edu/upperair/indices.html

HTML-TXT files were first download for every sounding. Script for parsing was running after. TXT or CSV files, where data are sorted by level or characteristics, were created by bash script. Data from TXT-CSV files were used in Excell file with complete statistics and lot of graphs. Formulas for statistics are different for year with 365 and 366 days. There wewe four soundings per day until year 2012 - 00 06 12 18 UTC. But only three soundings per day have been used since year 2013 - 00 06 12 UTC.

Parsing HTML file is not so easy, and sometimes - bad data are coming. Values have been checked, however, there can be still bad data. Graphs for levels and indexes are created from every sounding, it means 1460 resp. 1464 values per year until 2012 and 1095 resp. 1098 values per year since 2013. There are missing data for some or all levels during some soundings, but not so often.

DATA FOR DOWNLOAD

TXT and CSV files for all Czech, Slovakian stations with aerological soundings - Praha Libus 11520, Prostejov 11747, and Poprad Ganovce 11952. There are more versions for Praha Libus 11520 - period 1973-2017, 1973-2012 and 2013-2017.
