When I first wanted to use OriginPro to make 3D plots for my Raman and photoluminescence data I struggled to find a solution for little problems for hours. It was not like I had no one to consult, but I wanted to figure it out myself because the same philosophy with learning things previously has helped me immensely in learning things with authority and developing my own characteristic style, by putting in an extra amount of time and hard work.
Check with your university, there’s a big chance that they offer you students a free copy of OriginPro. It is an amazing piece of software, easy to learn and can make plots beautiful enough to be published in Science or Nature.
However when I was toiling through things, I also wished someone who had gone through the same thing could have documented it somewhere. Not surprisingly, no one had. So I wanted to. Here it goes.

In the year 2001, between 25th July and 25th September, people from the Indian state of Kerela (Kottayam and Idukki districts) experienced a bizarre oddity – The Red Rain of Kerala. Sporadic heavy downpours of mysteriously colored water left the people of Kerala dazed. More recently, red rains were also seen in parts of Sri Lanka between 15th November and 27th December, 2012.
Yellow, Black and Green rains have also been reported several times since 1896.
Red Rain of Kerala – Studies
A study conducted in India showed that the rain was colored because these raindrops contained millions of spherical and oval red particles which had an internal structure. These things looked like biological cells. Initially, when scientists weren’t able to confirm the existence of DNA (a fact which has baffled scientists) in them, in spite of an internal structure present in the cells, some started claiming that the origin of these red particles was extraterrestrial, possibly, coming from an exploded meteor.
Later the mystery was solved, the presence of DNA was confirmed and a study, destroying popular media claims, concluded that the red rain of Kerala had been colored due to airborne spores originating from a type of algae. There was nothing alien about it.
The unusual color of the rain was due to the presence of a unicellular micro-organism belonging to Kingdom Protista, of the Phylum Euglenozoa, known as Trachelomonas. Trachelomonas was the main cause of reddish downpours in other regions of the world as well.
