Our project “SindheX” mainly focused on the major climate extremes occurring in Sindh province of southern Pakistan. Therefore, the daily data is collected from the nine weather stations Jacobabad, Mohenjo-daro, Rohri, Padidan, Nawabshah, Hyderabad, Chhor, Karachi, and Badin. Table 2 shows the geographic coordinates and altitude of the stations. Temperature, relative humidity, and precipitation data is provided by Pakistan Meteorological Department, for a period 1980 - 2013.The sea surface temperature data is obtained from the UK Met Office Hadley Center, for the duration 1891 – 2015. The datasets used in the project are listed as follows

    1. Maximum Temperature (°C)
    2. Maximum Relative Humidity (%)
    3. Precipitation (mm)
    4. Sea Surface Temperature (°C)

Temperature extremes are estimated during summer season (May- September). The wet-bulb temperature is calculated using an empirical equation developed by Stull (2011). Precipitation extremes are restricted to summer monsoon (June- September). Sea surface temperature extremes are analyzed in pre-monsoon (May-June) and post-monsoon (Oct- November).
