Data

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).
