Question: Data Subset for OMHCHO: OMI/Aura Formaldehyde (HCHO) Total Column 1-orbit L2 Swath 13x24 km V003

Re: Data Subset for OMHCHO: OMI/Aura Formaldehyde (HCHO) Total Column 1-orbit L2 Swath 13x24 km V003

Many thanks for the additional information. I understand why it was difficult to crop also the pixel corners due to dimension size restriction. Generally, with the other dataset, I have worked with, an additional dimension of length 4 is created for pixel corners, and hence the size of pixel corner ...

Data Subset for OMHCHO: OMI/Aura Formaldehyde (HCHO) Total Column 1-orbit L2 Swath 13x24 km V003

I want to provide feedback about subset data download for OMHCHO V003 data. In the data subset, almost all the variables are cropped, but the corner points of latitude and longitudes (e.g. PixelCornerLatitudes and PixelCornerLongitudes) are not cropped. Hence they have a different dimension size as ...

Question: Reanalysis data for 36 point locations

Reanalysis data for 36 point locations

Hi,
I'm interested in time series of daily precipitation rate data for 36 point locations in the European Alps from several reanalysis datasets (ERA-interim, ERA-5, NCEP/NCAR, MERRA-2).

Is there a way to obtain this data without the need to download thousands of files?

Question: Albedo data

Albedo data

I am checking the albedo data for one location: lat 37.521, long -1.828. The values are not too bad, but I wonder if they are totally correct or maybe could be better, because of the location is to 25km from the sea. In a previous enquiry (other location), you commented the Nasa grid to check the al...

NLDAS coordinate convention questions

I have a simple question about the coordinate conventions in VIC hourly data. I downloaded these data in netCDF format and am working on translating them to raster format in Python for use in hydrology research. Are the longitude and latitude values to be interpreted as centroids of each grid cell? ...

Question: Surface windspeed in tavg1_2d_flx_Nx (M2T1NXFLX): Surface Flux Diagnostics

Surface windspeed in tavg1_2d_flx_Nx (M2T1NXFLX): Surface Flux Diagnostics

Hello,

In this dataset there exists a surface windspeed measurement. What is the height that you would consider to be the surface: 2m or 10m ?

Intuitively, I took it as being 2m. However, it is inconsistent with another data source I am using that has winds at 2 m.

Corrosion risk due to relative humidity

I am working in one project, trying to quantify the corrosion risk of bridge in Texas. One important step is to get the annual relative humidity in Texas. So I want to get the access to it.
I can’t create a ASDC account. Could you help me with that?
