I am new to GEE. Now I want to use the gldas air temperature variables data from March 1st to June 30nd, But the data temporal resolution is 3h. So in one day , there are 8 scenes in use. Now I want to use the mean value of 8 scenes and export it as the day by day. But I have no idea how to set the loop to get the mean temperature data every day. Can anyone help me with code for this?
Dear Hongda,
To use nested loops (data), try using Python - see video (Average Rainfall – Python https://www.youtube.com/watch?v=-M5obHIRf1M
You may also visit the NASA GESDISC channel for a quick look at Giovanni features. Please register with Earthdata and login in order to gain full access to data and services within Giovanni.
The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) provides access to LDAS datasets using multiple methods, including HTTPS, GDS, and the ability to subset spatially, temporally, and/or by variable:
GLDAS – https://disc.gsfc.nasa.gov/datasets?keywords=GLDAS
NLDAS – https://disc.gsfc.nasa.gov/datasets?keywords=NLDAS
NCA-LDAS – https://disc.gsfc.nasa.gov/datasets?keywords=NCA-LDAS
FLDAS – https://disc.gsfc.nasa.gov/datasets?keywords=FLDAS
These datasets are also available via Giovanni – https://giovanni.gsfc.nasa.gov/giovanni/#. Giovanni is an online application developed by the GES DISC that allows researchers to rapidly explore data, so that spatial-temporal variability, anomalous conditions, and patterns of interest can be directly and easily analyzed online before optionally downloading the data. Supported download formats include NetCDF, GeoTIFF, and KMZ.
Sincerely
Princ Ivan
