Do you believe in Climate Change?

There are some questions out there regarding is that climate change is true? well, recently I worked for a project that forced me to look at various data including long-term rainfall and temperature data. This is rainfall data in Australia. If we compared the long records with current rainfall data, surprisingly, the four months cumulative rainfall has more than any annul record from 1859 to 2021. 

I also looked at the climate data from Singapore, the temperature has rise significantly. If looked at long-term trend, we can conclude that temperature is getting higher.

In term of rainfall, it is going up and down as a normal pattern. But if look at the average rainfall, we can see that it is going up. 

You may believe or not, but this a real data that tell you something happening in our climate. Another question is do we need do something or no need as it may just a climate change. 

Data Analysis

When you work with hydrological data, it is always good to screen and assess the quality of data. These kind of questions must be answered such as how many years of available records? and missing data. Rainfall data will useful if it is no missing data. The missing data will cause the values are less which subsequently cause the rainfall accumulation is less.  One of software that I commonly used is HEC-DSSVue. 

Besides, for visualization purposes, this software can be used to manipulate data using math function and for database input that will be used in HEC-HMS or HECRAS (see example of rainfall data below).

ProjectLibre

 It is always interesting to learn something new. A few days ago, I have learned ProjectLibre and I think this is cool that every project engineer/manager must learn about it. If you have familiarized with  Microsoft Project, then this software is exactly the same. The best one is that this software is free. 

You know whatever project is running, you need to monitor the progress and before that, you need to have a plan internally or you need to share with you client. This software can help to do it.  As an example, see Figure below showing the ProjectLibre for a simple kitchen and bathroom renovation project.

Beside for planning and update the progress, this software is also capable to manage manpower and budgetary. You can assign manpower as you wish and control the budget.
