Hello there,
I'm looking for chlor_a monthly climatology of 2003-2018.Here (https://oceandata.sci.gsfc.nasa.gov/MODIS-Aqua/Mapped/Monthly_Climatology/4km/chlor_a/), there are 6 data ( Jan - June) of monthly climatology of 2003-2018. Data name are given below...

But other 6 data (July- Dec) are not available for 2003-2018, its for 2003-2017. Such as....

How can I get chlor_a monthly climatology of 2003-2018 from July-dec. The name of the data will be......

Since the Aqua mission started in July of 2002,  the monthly climatologies for July - Dec begin in 2002:

If you need the 2003-2018 period climatologies, you can download the monthly composites and create the climatologies using SeaDAS.

Thanks, towens,
As MODISA mission started from July 2002, I can't get data before that period.
To make a composite image from 2003-2018, I need to install Ocssw and I have that. But it needs a huge time for my PC to composite such file as my pc configuration is low (4gb ram, core i3, windows 10 + wsl). For this reason, I asked if there any climatologies data can be found that is previously prepared.

But anyway, Thanks for your information.

Regards.
