Welcome to our world!
Time spent on research is never wasted, I spent 4 months workig out what I needed to start with and built from there
I am not familar with that station but it looks like a Fine Offset clone

https://www.wxforum.net/index.php?topic=40730.0Its daunting but after a while you will start to refine your requirement:
- Composite sensor (multiple sensors in one piece of kit, simplifies mouting but compromise location) or separates (sensors in various sites linked together, permits optimal location but increased complexity of installation) which will in turn depend on your siting options
Connectivity requirement (connect to what using what and the power requirement)
Resilience/quality, especialy on an exposed site
Mounting requirement
Budget!!
There are numerous resellers of FineOffset kit, many described in the link and available from various websites, including various flavours of amazon
The Fine Offset system is modular and allows you to grow your system with your developing interest and within budget and connect to the internet and computers (all sorts) via gateway units where you can run various software products to analyse and manipulate your data and/or send it on to other weather services
Ther are other options - Davis is highly regarded and may be more suitable for your purposes and climate
There are users of most systems on these boards so once you have done some research ask questions!
