Re: Economics and data visualization

Hello. My initial answer would be to examine atmospheric chemistry species indicative of industrial emissions, such as nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), methane (CH4), carbon dioxide (CO2), and tropospheric ozone (O3). Also, indicators of air quality, like atmospher...

Re: GLDAS PRECIPITATION DATA

Hello, GLDAS does not have any 1 km resolution precipitation data products. The best available spatial resolution is 0.25 deg. FLDAS has monthly 0.1 degree data, and rainfall flux is one of the variables available at that resolution. FLDAS monthly data set landing page: https://disc.gsfc.nasa.gov/da...

Question: Aggregating runoff data in a hydrological catchment
Replies: 1

Re: Aggregating runoff data in a hydrological catchment

Here is the answer, a collaboration between our SME and a GES DISC staff scientist. 1. GLDAS total runoff is the sum of subsurface runoff “Qsb_acc” and surface runoff “Qs_acc”. 2. Since the units of “kg m-2” as 3-hour accumulation is correct, there is no near term plan to change the units in the Ne...
